• ESX 3.5 is very slow in the workstation 6.5.2

  Hi all

  For test purposes, I installed ESX3.5 in my 6.5.2, work station it will take a very long time to get the final screen. Can u please help me solve this problem.

  the details of my office are:

  Motherboard - intel DG31PR-LGA775 socket.

  iPROCESSORquad core 2 ntel Q9400 2.66 GHZ, 6 MB cache L2, LGA 775 95W(it has the feature of the technology intel VT).

  RAM - 2 GB DDR 2

  HARD - 160 GB SATA DRIVE

  working on the OS platform: windows 2008 Server

  I've tried editing the .vmx files, I followed all the steps specified in "How to install esx3.5 in workstation 6.5" also. but still, it will take more than 30 minutes to run a single esx [ram allocated is 1024] in a worksation.

  What will be the question. Help me solve this problem?

  Yes, I think that VT - x is locked on the feature control MSR.  However, the CPUID instruction reported that your processor has no ability of VT - x.  Before, we look at the feature control MSR, the CPUID instruction must declare that the processor is able to use VT - x extensions.  To resolve this problem, you need to update your BIOS.

• Very slow network with 10 Workstation and Windows 8 / 8.1 Windows

  Hello

  I come to you because I have a problem with the network with 10 Workstation and Windows 8 / 8.1

  In fact, if I copy files from or to a virtual machine with my host of Windows 8 by sharing Windows (SMB / CIFS), it is very very slow and unusable.

  Example: My host is a Windows 8 x 64 and Windows 8 x 64 host: transfer speed is about 100 or 200 KB/s and often 0 KB/s (transfer seems to be paused).

  With a guest Windows 8.1, same problem.

  After many tests, I also tried with Windows PE 5 (same kernel as Windows 8.1): same problem, unusable.

  But, miracle, if I use "Utility MSI - X OFF" Intel, I reboot and the problem disappears.

  There:https://downloadcenter.intel.com/Detail_Desc.aspx?lang=eng & DwnldID = 18946

  Someone in this community, said that it have the same problem and a workaround solution was not to use Intel e1000e but e1000 then: I must admit, it works.

  With e1000, speed is around 30 to 60 MB/s and stable.

  But, by default, 10 Workstation e1000e value when I create a new VM Windows 8.1, so it's a problem... Do not manually change for each new virtual machine and explain this to my students.

  Please, you can reproduce this bug and fix it?

  Thank you very much.

  New workstation 10.0.2 fixed this bug. Perfect.

• Very slow speeds - Workstation 8.0.2 suspend

  I don't know if it something that I did, or the recent update of the workstation, but it is now still holding to suspend my (fairly large) guests. A guest of Vista is by far the most powerful, although a small enough guest of Windows 8 is also very slow.

  All my guests are split into 2 GB sizes and all have recently been "shrunk"---(erreur?). All are run under a Windows 7 host.

  Does anyone have advice to try to improve performance short dating back to 7 Workstation?

  > All what you have tried so far work?
  Hi Dave
  I had the same problems with suspend time WS 8 and 9.
  The only thing that has really worked to change my habbit use suspend rather than turned off when done with a virtual machine.

  With 9 WS, I expected that suspend one of my typical virtual machines may mean that the host can (often) to do nothing other than just suspension than a VM for a time up to 30 minutes or even an hour complete (often enough to see!)
  I tried everything I could think off, but nothing is really - I have never used WS so rarely that this version 9.

  I run 10 now and downtime are close to what we were used with 6.5 or 7

  If these problems seem to be fixed in WS 10 - at least for me.
  But before you change - control because WS 10 different problems

• Ubuntu 11.04 very slow after upgrade to VMWare Workstation 8.0

  Hello

  After the update to VMWare Workstation 8.0 my Ubuntu 11.04 comments system (which worked very well with Workstation 7) behaves very slow sometimes.

  Slowly I want to say first that it is very laggy when I scroll conent inside windows, and also when I move windows.

  And with sometimes I want to say that this is not always the case. Sometimes, everything works fine for 1 or 2 hours and she begins and, sometimes, that's the problem immediately after starting Ubuntu.

  The problem occurs when restart Ubuntu does not help. But what is stopping Ubuntu and also restart VMWare Workstation on the host (in my case Windows 7) completely. When I do this and I'm lucky everything seems normal again for a while (1 or 2 hours). After that starts all over again.

  VMWare Tools is installed and the comments system has more then enough resources. I also improved the virtuale image to the latest version so that the new features in Workstation 8.0 are available.

  I first thought that maybe it's a RAM problem but the system begins to lag when there is still 1 GB + RAM available and 0.0% swap used.

  Any ideas what I could do? This is quite annoying...

  Hi LucD,

  I've found a workaround:

  When I run the import-PSSnapin I noticed (with wireshark) a lot of traffic failed to WAN addresses, so I set myself, in Internet Options a false proxy (127.0.0.1), excluding the proxy DNS of my domain active directory name (so I can connect to the virtual center without going through the wrong proxy)

  Now is the time of execution:

• Very slow view using OS x client for Windows 8 RDP

  I'm having a problem of strange performance to help the customer to view for OSX and connecting to a remote desktop in Windows 8. I'm the last side connections to the same remote workstations using a windows on the excellent work of the RDP client and client and server versions. No performance problems. I'm a bit at a loss as to what could be the issue.

  Context menus in Office remote work quickly but running programs, opening and closing of windows, etc. is very slow. No conflicts or hogging on the remote system, nor the client resources. All connections PCOIP or RDP sessions to other workstations (which are all Windows 7) work perfectly without any problems. Any help in troubleshooting is appreciated.

  Hello

  When connecting to the remote with the Protocol RDP of Mac View Client Desktop, it will use the image of high quality as a default value for the connection of the DRC. MS RDC app is a very old application, there is no new version for so long and there are no updates to improve the performance of this specific to the new Windows operating system (Win8/8.1/2012). Perhaps the reason for the performance on Windows 8 with the DRC issue.

  If you are using the RDP protocol client Mac view, please change display settings for the Remote Desktop Connection (RDC) first app. And then reconnect directly remote desktop via IP (without customer view) to check if the performance is somewhat improved.

  Menu at the top of the app DRC: DRC-> preferences-> display

  Try to change some parameters like the attached screenshot shown.

  

  If it works, you can replace the template file RDP for the Mac View Client app with steps below:

  1. download the attached template file ' vmware - view.rdp.

  2. copy and replace the file in the Applications/VMware view Horizon Client/Contents/Resources/vmware-view.rdp

  3. exit view Mac Client app

  4 restart Mac View Client and connect to Windows 8 desktop via RDP Protocol

  Thank you.

• VERY slow mouse on my computer 9

  I have been using the same computer to Core i7-920 for four years now.  Since I upgraded to VM Workstation 7 to 9, the mouse is very slow.  I have to double, triple and sometimes quadruple click here to get an answer.  There are times when there are 30 second delay between clicking and something happens.  This occurs on the virtual machine that I've had for a while and the new virtual machine that just places I.  I bought a new, faster, internal hard drive for the virtual machine on and which did not help.  It's to the point where using VM Workstation costs me more time than it saves.  Any suggestions?

  The log file contains a large number of waiting times for the floppy drive, inputs on updates to automated tools as well as automatic snapshots. Please check the VMs and disable 'Connect to light' for the drive diskette and CD-ROM, and then in the 'Options' tab value "VMware Tools" updates 'Manually update' and 'Snapshots' set "Just power off" (unless it's something you want or need).

• PR CC Pro very slow on the new custom build and lag?

  I just finished my new workstation of the construction and the first port of call was the first Pro CC installation! This version was specially designed for video editing, but I'm sad to discover that Premiere Pro is very slow and laggy. There is a lag when you click too quickly, clicking on between lag and the causes of windows (mixer audio/source/effects clip) a shift and the new window takes a second to load if you scroll down. The report is the biggest problem it will take A long TIME!

  When rendering I noticed that my CPU uses only 40 to 50%. I don't know if this is normal. If someone could help me use my material, I would be very grateful!

  I tested Premiere Pro using some HD footage that I ripped off of YouTube. Acceleration GPU of Mercury Playback Engine is selected.

  Could be. Or could with this material, you need different settings.

  I have a new machine and the manufacturer has played with a lot of things... it is Variant Canyon one hell 4-core i7, primary core @ 4.6Gzh, other three to 3.5 Ghz, fsb too clocked at 166 Mhz and curiously, RAM & the three slowest nuclei have been slightly underclocked due to the way which they interface actually more quickly with these settings. By report to my previous machine, also a 4-core, it's SMOKING. On first commissioning with everything to 'standard' settings, it is faster but not Mary. At the time where he played with the settings, wowie... just kazowie note the difference in performance with changing parameters, you can re - think about the configuration of your machine. Although, of course, you can correct that there is a problem in a hardware store.

  More on the page of the Tweaker is discussed for the fsb, CPU, and frequencies RAM shook everything to get as much flow. There are things like that that can make a huge difference in performance.

  At this point, I can't emphasize too much on using the test on the page of the Tweaker to see where you machine is doing well and where it chokes... the test is a folder compressed with a file media & project plus a logging program. You extract all, install the deposit return program on your machine, import the project into PrPro with his single on the chronology of 30 seconds and run an export. The sequence specifically chose the applied effects so that every bit of material are in tatters on... CPU, RAM, GPU, fsb and disk read/write. You download the results of the logging program and to obtain an accurate statement of how perform every part of your machine. This would probably tell you more than anything else right now.

• Win2008r2 x 64 very slow VM running under Windows 7 Ultimate x 64

  I have searched in the nets and have seen similar problems. However, I just wanted to see if anyone has had the time to fix the issues that I am experiencing. Bascially,: the performance is so bad when you perform an initial installation developer that I shudder to think of what it will be like in normal use. You name: copies of the host is slow, running installs it variety takes an eternity, but the classic is when I installed windows 2008R2 x 64 has taken more than 6 hours to format the 80 GB drive, copy files across and complete the installation.

  In any case, I try to configure a 3.51 .NET / MOSS 2007 Developer of windows 2008R2 x 64 installation. I do this on a labtop to 2.2 Ghz AMD Turion X 2 recently acquired running Windows 7 Ultimate.x64. I have 4 GB of RAM and the usual WIFI Attheros. First of all, I chose VMWare Server 2.01 because it supports USB2 and 64-bit, instant clients while Virtual PC 2007 does ' t.

  Win2008R2 comments

  1. Memory of the VM value first 1 GB 2Gbto see if ifit makes much difference

  2. 2 vCPU

  3. CDROM installed

  4. VMWareTools... haven't tried to install it but page left summary seems to indicate I have not, not sure if it would substantially improve performance.

  5. Bridge networ_k_

  Things to try

  Looking at this networking wire Workstation 6.5 on Windows Vista x 64 host - bridged is broken! The performance of the network very slow folder shared! I should conider

  1. Check that in the laptop BIOS VT is enabled by default - I assumed it was.

  2. Reduction in the number of vCPUs to 1

  3. Drop the CDROM

  4. Ensure that VMWare Tools is fully installed

  5. Deactivation of windows 7 next host card connection network Local - & gt; Configure - & gt; Properties - & gt; Advanced: Large Send Offload v2 (IPv4) and Large Send Offload v2 (IPv6). Remember I'm toward the life of a wifi connection, so this may or may not have any effect

  6. Anything else anyone can think please...?

  I guess I just need some advice to help solve this painful problem, as it is to distract me from what I should do on the guest o/s...

  If you have done nothing yet, try first assign to VM 1 GB and 1 vCPU. Do never set more than 50% of memory available VM vive.

  About RDP: it connects OK? Check the system logs and firewall.

• Access the disk very slow and steady

  Running VMWare Workstation v6.5.0-118166-Build, on Windows XP SP3 host (Dell Optiplex 755).  VM sessions are stored on internal 500 GB SATA 3 GB of disk.  After Windows XP SP3 is started in a virtual machine session, system response seems very slow; IE, by clicking on an icon takes several seconds to respond, launched apps take unusually long to load, etc.  Symptoms persist for several minutes after the start of the session XP.  Meanwhile, the indicator disk in VMWare Workstation shows status bar access the constant disk.

  I defraged the session, both within Windows and using the VMware Workstation defragmentation utility.

  Anyone have any ideas why this disk access continues for so long?

  Thank you

  Jack

  Yes, snapshots are, as well as all the contents of the folder of the virtual machine.

  Well, it seems that you have.  Using a virtual machine of independent origin identified the problem as long as the virtual machines themselves, who all had the same problem, because they inherited from their parent, all 46 chromosomes from the same source.

  So unless you want to determine what virtual machines is defective, you may be ready to mark this as a response.

• WebHelp TOC does not display in Firefox and loads very slow in IE... advice?

  We have recently migrated to a webhelp online system so that we do not have to distribute documentation with our software.  We organize the webhelp documentation on our Web site and it's supposed to be accessible from our software.  Our problem is that the table of contents are loading very slowly in IE and does not at all seen Firefox.

  When I run the help locally (on our network or on my workstation), the table of contents works very well.

  During the last hour, I added the script to force the table of contents of synchronization (found on the site Web of Peter G)... and it did not help.

  Any advice on where to look?

  I can pm our URL for the help, if someone thinks it will help them to diagnose.

  Thank you!

  Jim

  (currently using Robohelp 8)

  No problem. Just load the page with the active Console tab. Then select the errors and you will not get the errors.

  Note: The table of contents are also very slow to load in Chrome. You have quite a few projects merged, so be sure that you set the correct speed optimization.

  The help of opening shows two errors in the Firebug console. I get a 404 on a missing file error: "" NetworkError: 404 not found - http://www.foodpro.com/help/release_2.4/webhelp/mergedProjects/FPUSRPRF/whxdata/whtoc.xml".

  The errors indicate that the merged projects 'checkfiles' and 'FPUSRPRF' are missing. I suspect that FF choke on the missing mergedProjects/FPUSRPRF/whxdata/whtoc.xml. Still, execution stops after that.

  But perhaps a merged help guru can tell you more.

• very slow Powerbook fine, iMacs

  My family uses 2 iMacs (1 2013, 1 earlier) and an Apple Powerbook at home. 2 iMac is incredibly slow, but the speed of the Powerbook is fine. IMacs both have a lot of unused storage and memory and I completely restored two iMacs and deleted unnecessary files, but they are very slow. I have everything back up on Dropbox and wonder now if the slowness is something to do with the combination of the signal at high speed and by using several connections of Dropbox in the House.  We have a Virgin Media Hub Super 2ac with advertised broadband router of up to 150 Mbps. I made a speed control using www.speedtest.com and the download speed is 105.81 Mbps and download speed is 9.70 Mbps. Any ideas anyone?

  You can view a report of etrecheck for later analysis

  www.etrecheck.com

  but I would like to disable and remove dropbox to test the system and if they improve the problem there.
