  Someone had problems with VMWare Workstation running Windows 7 64 bit? My computer hangs when creating the virtual machine guests. I also have VirtualBox running very stable with Windows 7. I was wondering if anyone has had problems? VMWare has a new version of 7 who suppose to be stable with Windows 7. I am skeptical. Your comments are welcome.

• Very slow network performance

  I have a Dell T610 running ESXi 4 with a pair of built in maps network gigabit Broadcom BCM 5709, to which I've also added a gigabit dual port Intel 82576 NIC they are all plug a Cisco 3560 24 ports switch. There are a couple of virtual machines on this computer and there was near zero, a network, or activity of the CPU during the following tests as they were made during off-peak hours.

  I noticed a few updates takes a long time to download and, after completed and restarting the virtual machines, I decided to perform a speed test that indicates the very slow network performance. But the performance is slower on one NETWORK card to another. Reduce the ports available to virtual machines on a single NETWORK card, that's what I got.

  Using Speedtest.net as a gauge running on a dedicated XP Guest:

  The Broadcom and Intel befriended 5Mbps showed and sometimes 10 Mbps.

  Only Broadcom showed between 13-18Mbps from one trial to another.

  Intel showed only 4-5 Mbps. never more than 5 Mbps!

  Physical work stations connected to the same switch showed 45Mbps repeatedly!

  All ports were originally configured as auto negotiate. I tried locking time ESXi and the Cisco switch to 1 GB Full duplex with no significant difference in the overall performance.

  Has anyone seen this? Have you found a solution?

  I got a similar promblem - found that the VM - NIC has been set at the 'flexible' type and VM-Ware tools were not properly installed.

  As I was not able to install (linux, no gcc), I've removed the NETWORK card and put in again as an adapter 'e1000 '. From here, I had transferrates as expected ;-)

  I hope this helps...

• Linux host freezes with 10.0.6 Workstation and Windows 7 comments

  Hello

  
  

  I am now quite desperate because it is really preventing me from doing my job.

  
  

  I deleted Windows and I installed a fresh Kubuntu 14.04.02 (LTS) with 64 bit under my desk. I also installed VMWare Workstation 10.0.6 to run my development machines. I am now having serious problems:

  
  

  Every now and then, my full host is the gel if I'm running a Windows 7 virtualized on my workstation. The mouse only moves very slow and all the windows are very (!) slow response. My CPU monitor list all 4 CPU to 100%. If I managed to open the monitor system (or top on the console), I can see that vmware-vmx and kwin burn most of my CPU resources. If I wait 10 seconds to a minute, the system becomes usable. Now CPU goes down to normal. But as soon as I start to move a window (any one), the thing is happening again.

  
  

  Symptoms in short:

  • HOST: Linux Kubuntu 14.04.02 (x 64) on Intel i5 CPU with 8 GB of RAM and running on SSD (ext4).
  • COMMENTS: Several Windows 7 (x 32) several software running. Assigned 1 CPU and 1 GB of RAM. It comes on several guest computers.
  • Every now and then, all my CPU taking nearly 100% 4. The host CPU is used by vmware-vmx and kwin (used above) processes. Sometimes after 15 minutes, sometimes directly after turning on the prompt. No idea on reason.
  • Host of mouse, Windows, and OS works very very slow.
  • Meanwhile, Windows 7 virtual machine is inactive! Energy saving or screen saver are all off!
  • If I manage to run Taskmanager guests, I don't see an action (sometimes TaskManager itself using 60% of CPU!). Looks to me that the host is down, not comments!
  • My host is running an SSD (256 GB).
  • VM log file does not show something during this phase.
  • VMware.log attached.

  
  

  What I tried:

  • I disabled 'Accelerate 3D' for all my virtual machines.
  • I have re-installed VMWare Tools on the guest computers.
  • I run VMWare workstation with vblank_mode = 0/usr/bin/vmware
  • I recreated the machine with less hardware as possible and recharged the .vmd.
  • I converted to virtual prior to the current format format disk image (VMWare asked me to the front step, I said 'yes').
  • I have inserted a separate network card (NIC) and disabled the network card that is embedded in the BIOS.
  • I disabled the onboard graphics in the BIOS and added a card NVIDIA GeForce 8400 PCIx16 (using NVIDIA binary drivers provided by Kubuntu).
  • I removed the CD-ROM of the virtual, Audio computer, diskettes and any unused material.
  • I have tried using cpulimit strangle vmware-vmx and kwin on my host, but without success. System remains unusable in this situation.

  No success at all.

  Is there anything else I can do to put my environment in a productive state? You can imagine that this always happens in the worst situations :-(

  Any ideas?

  Thank you!

  I found this page:

• XP 64 bit VERY slow to access the directories and network drives

  We have some Dell Precision workstations of the very high-end with 24 GB of RAM and 4 CPUs to four hearts.  When users use workstation on a network drive, it may take up to a minute before the directories appear.  The flashlight may appear.  This latency is frustrating.

  However, in Windows Explorer, it's almost instantaneous.

• Recent problem with very slow internet browsing on all browsers Windows Vista Home Premium 32 bit

  Separated from this thread.

  Hi all I'm having the same issues as Theresa in the thread above split. I have Vista Home Premium 32 bit service Pack 2 with all the installed updates (automatically done!).  Within 3 months, this PC at home that was formerly an excellent navigation device became very slow when you browse using IE, Firefox or Chrome. It takes 30 to 50 seconds to load any web page (Yahoo, eBay, etc.). I followed all the instructions suggested to Theresa in SafeMode by Bill Smithers. Resulted in nothing other than a few cookies and Wetherbug I killed. I also run McAfee total protection and Spybot S & D every 3 days with nothing found.

  I have reset my browsers to the specifications of the factory without change.

  Comcast is my internet provider high speed and my speedtest returns 65 - 75 MB/s download and 11 Mbit/s upload very regularly. I connect directly to the bridge. I had Comcast out and they swapped unity Arris of a unit of Cisco beefier but that changes nothing. Other devices on my network domestic perform very well and do not have this problem.

  When I browse a site the CPU spikes up to 88% use in 45 seconds and is stable at 50% usage 1.7 GB memory.

  The only thing I can infer is at this time that something happened to the operating system during automatic updates or some other setting has been changed.  I could use any help or suggestions you may have! Otherwise, I love this OS and have not had any problems. Thanks, Dhoffa

• Very slow performance with Windows 7 on i7 Quad

  I bought my wife a Lenovo E530 i7 quad with screen 1600 x 900 and running Win 7 in September 2012. Previously, she had an Asus Core 2 Duo also with Win 7. The laptop is used to picture (scanning, editing, cataloging) work, family, the navigation and email history.

  The E530 was desperately slow at the beginning. Not better, not faster than the Asus. Performance seems to vary from slow to excruciatingly slow.

  Features include:

  -very slow to open programs

  -slow to react to the choice of menus and clicks

  -slow to react to the touchpad

  -scrolling is not smooth, vibrates, much worse than Asus

  -often distorts the sound and video, audio stutters

  -IE9 make often video has properly - green band across the bottom with the rest of the colors shifted upward - change the video quality will fix it sometimes

  -very slow internet response compared to the other machines on the same network of navigation.

  However, startup speed seems to be OK.

  I spent weeks (months?) through the forums, verification of updates, deletion and restoration of various programs and drivers looking for driver clashes. I tried the clean boot with only Windows drivers and various other combinations, and it made no difference.

  For a long time wifi would be max 54 Mbps but somewhere through the process he begins to operate at up to 300Mbps.

  Nothing seems to stand out in reports on health of the system and the event viewer. Windows experience scores seem to be everything I expected from my older i7.

  Resources and performance monitor reports a problem with the hard drive:

  The average disk queue length = Max 16 = 106

  %Idle = 0

  Disk read/s Ave = 0.093 Max = 3

  Disk sec/Transfer Ave = 0,067 Max = 1

  Disk s/write = 0.022 Ave

  Even when the computer runs slower the CPU usage, and memory usage is not mounted and ceiling ever.

  SFC report any breach of integrity.

  FixIt MS - slow performance does not detect any problems.

  The disk check is not a problem any.

  It's so frustrating that my wife threatens to throw it in the trash and buy a Mac (the horrors :-)).

  Any ideas on what I might have missed or what I should look at?

  Thank you

• VMware in network bridge: Freezed host with WS6.5 and Windows Vista x 64 or Windows 7 x 64 host operating system

  Hello

  I have a problem with VMware Workstation 6.5 on 64-bit Windows host.

  First, I installed VMware Workstation 6.5.0 118166 on my x 64 Windows Vista SP1 host, and I had a weird problem when working with network on my host system, no matter there is a guest running or not. The problem is when I try to connect/disconnect from VPN connections or plug/unplug my network from my LAN socket cable, etc., host OS freezes suddenly with no answer to anything whatsoever, no movement of the mouse, without strikes, nothing.

  After sometimes, I installed Windows 7 Beta 7000 x 64 on my computer and have no problem with it until I installed VMware Workstation 6.5.0 118166 on it: the gel problem once again. I thought it may be a problem on this specific build of VMware, so I downloaded and installed the latest version (6.5.1 126130) on my system, but the problem persists.

  After playing with a large number of settings, I find that if I delete the service "VMware Bridge Protocol" of my network card, the problem does not happen.

  I searched the forum but I can't find anything like that, so I wonder if anyone can help me with that?

  My network card is an edge ' Realtek RTL8168B/8111 Family PCI - E Gigabit Ethernet NIC (NDIS 6.0) b ' on my card mother Gigabyte GA-MA770-DS3.

  Other features of the system:

  AMD Athlon 64 X 2 5200 + CPU

  6.0 GB of RAM

  Seagate ST3500320AS SATA HARD drive

  nVidia GeForce 8600GT 512 MB video card

  Thank you.

  Which driver version you have installed for your network (NIC) card?   This link shows a version of driver Vista/Win2008 6.216 (dated 2009/02/26) available.  The same driver should work as well for Win7.

  If the above does not resolve the problem, view the properties for the NETWORK adapter and temporarily disable all 'Task Offload"or other characteristics"discharge"to see if that helps.

  Hello

  Here are several documents that might be useful for you:

  Using the LabVIEW shared Variable

  Troubleshooting network-published static Variables

  How can I use shared Variables to transfer data from Vision Builder for Automated Inspection (VBAI)...

  You can also try something. To do this, you must go to the EXE VBAI here:

  For 32-bit machines:
  C:\Program NIUninstaller Instruments\Vision 20XX\ VBAI

  For 64-bit machines:
  C:\Program Files (x 86) \National Instruments\Vision VBAI 20XX\

  Right-click on "Vision Builder.exe", and then select Properties.  Make sure "run this program as an administrator" is checked.

  Click OK, and then try to rerun VBAI. You may need to redeploy the variables in the variable Manager until they work properly.

• Time of very slow start with SSD

  Hello

  I spent the last few days the net trying to find a solution to the boot of win7 very slow but have led to nothing so far trawling.
  Im running Win7 Pro in bootcamp on a Macbook Pro with an SSD and 16 GB of RAM, but don't get a time horribly slow start, including a screen black (with usable mouse) for a long time before the watch office. I am not able to do a reinstall but would like to get the issue resolved if possible.

  So far, I checked the event viewer to see there are problems and I don't see anything significant that the mere fact that each entry includes an 'Error' level, but I don't see what this error. I also used the process monitor to see what takes so long and there are a couple of processes which are time consuming and show a result 'Cancelled', one being svchost.exe 110secs (path: ...system32\drivers\etc) and the other 23secs Explorer.exe (path: ...appdata\roaming\microsoft\systemcertificates\my)

  I should mention that I'm very new to this kind of troubleshooting but would appreciate any help I can get!

  Thank you!

  The problem is that windows has been hanged in trying to restore network connections. Problem solved!

• In ESXi 5 very slow network performance

  We have recently updated one of our servers to ESXi 4.1 to 5. It's a Dell PowerEdge T300 with 24 GB of RAM. It used to run very fast, but after the network upgrade is very slow. We have another server that is still running ESXi 4.1 which runs very fast.

  I noticed the slowness of the network in Windows 7 and Windows 2008 R2 systems. When I copy a file from the ESXi 5 hosted VM to a physical machine on our network, I get between 2 to 4 Mbps. When I copy the ESXi 4.1 hosted VMS on the same physical machine, I get 80Mbps.

  I tried to disable TCP unloading on the physical machine and virtual (and both) computers with no improvement.

  I also performed a capture of the WireShark packages on one of the virtual machines Win 7. I noticed one interesting thing is that there was a lot of duplicate ACK packets when you transfer a file on SMB. I didn't know where to go to from there.

  If anyone has any suggestions, I would appreciate it.

  Check the BIOS of the server ESXI 5 and see if this physical NETWORK card sharing resource IRQ with another device and change it if it is.

• vSphere Home Lab: very slow network speed, I'm desperate

  Hello

  After many trials that I have finally found the right hardware build my vsphere home laboratory.

  This is my setup:

  ESXi1

  ASUS P6T Deluxe V2

  I7 920

  24 GB OF DDR3 MEMORY

  2 x Intel Pro 1000 GT Desktop Ethernet adapter

  2 ESXi

  i5-2500

  1 x Intel Pro 1000 GT EthernetDesktop adapter

  NAS

  ASUS P7H55-M

  Intel Core i3-540

  Windows Server 2008 R2 with Starwind iSCSI

  Realtek Gigabit Ethernet

  I have a Netgear GS108 where I plugged all the ethernet cables over my ADSL Modem, a Linksys WAG320N

  Everything is OK apart I have a speed very very slow in the network; for example ISO 2k8r2 server transfer I take 30 minutes

  After many trials, I decided to start from scratch, I just powered on my ESXi2 machine and reinstalled ESXi 4.1U1 from scratch and I installed the Client vSphere for my Client PC which have a Gigabit Ethernet card and is also attached to the switch Gigabit however, speed is still the same, 2/3 MB / s.

  The strange thing is that also the same speed very slow, I created a Server 2008 VM and installed iperf to landmark of network and I get about 600 / 700 Mbps, so I really don't know what I can do.

  I replaced the ethernet cables, also tried to connect the cables directly to the modem and also I tried with another switch, but the result is always the same.

  He is now a cable or switch problem because I tried to create an iSCSI drive and transferred a file of 10 GB of my Client PC to the iSCSI disk and I get about 120 MB/sec so is full Gigabit network speed.

  Also, I installed FileZilla FTP Server on the ISCSI server and tried to download and upload a file of 10 GB and the speed is never 115 / 120 MB/s.

  Really, I don't know what I do that, I'm really desperate.

  Thank you very much for your help.

  Routers are NOT created equal.  There is a business reason switches cost $10,000 - $20,0000 dollars.

  Netgear router / switch is just a very BASIC.  It's not classy company.  That's your problem.  Get a better switch that you don't need to spend $10,000 but probably a few hundred... a GOOD show for home switch...

• My computer is very slow. I tried everything and bought a tune-up, but it it a little relieved.

  I went to the site of Mircosoft and he gave me an analysis of updated drivers and that being said, I had 9 out-of-date drivers. As I am not very computer would it be a good thing to buy this and update drivers. Would it fold my speed and performance?

  Vista and Windows 7 updated drivers love then here's how update the most important.

  This is my generic how updates of appropriate driver:

  This utility, it is easy see which versions are loaded:

  -Free - DriverView utility displays the list of all device drivers currently loaded on your system. For
  each driver in the list, additional useful information is displayed: load address of the driver, description,.
  version, product name, company that created the driver and more.
  http://www.NirSoft.NET/utils/DriverView.html

  For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
  Control Panel - Device Manager - Display Adapter - note the brand and complete model of your
  video card - double - tab of the driver - write version information. Now click on UPdate Driver (this
  cannot do anything as MS is far behind the certification of drivers) - then do a right click - Uninstall - REBOOT
  This will refresh the driver stack.

  Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party with their
  own the software and drivers and all other main drivers that you have.

  Now go to the site of the manufacturer of system (Dell, HP, Toshiba as examples) (restoration) and then of the manufacturer of the device
  (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for the BIOS, Chipset and software)
  updates on the site of the manufacturer of the system here.)

  Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after each installation.

  Always check in the Device Manager - tab drivers version you install actually shows up. This
  because some restore drivers before the most recent is installed (particularly that audio drivers) so install a
  pilot - reboot - check that it is installed and repeat if necessary.

  Repeat to the manufacturers - BTW on device at the DO NOT RUN THEIR SCANNER - manually check by model.

  Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

• Very slow even with instances.

  Hi all, I am trying to compress a bunch of my own videos to save space. I have the compressor 4.2.2 on El Capitan 10.11.5, latest version of the software. My specs are:

  iMac 5K end 2015

  4 GHz Quad Core i7, hyper threaded to 8 logical cores

  32 GB of RAM

  AMD Radeon R9 M395X 4096 MB

  I export source H.264 in MPEG-4 h.264. I'm very slow sometimes, and this becomes even slower when I add an instance. Also, I edited the .plist preference file for the compressor and added more cases that I have been authorized by default because it was not maxing out my CPU. If I have 1 instance (as the compressor allows me) or 4 instances (which uses 90% of my CPU in the activity monitor), it seems much slower than the single instance. Why? My iMac is the most high-end model and a 8 logical cores, how is it unless its slow export when I use more instances? Its already very slow with just a single instance. How to speed this up?

  The Mac Pro is the most high-end model.  When transcoding to H.264 format, use not all instances.  The CPU has a built-in H.264 encoder that uses the compressor.  So bodies indicates compressor to ignore that and just do it via the encoding only software.  The speed you get is the speed you get.  Without knowing the length of your videos, what are their original format and the codex, or how long they take, I have no way of knowing if your Mac is slow or if you expect too much of him.  This information would be useful.
