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

• 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...

• (Redirected) All new Inspiron 3647 desktop PC has very slow download speeds.

  We live in very slow download speeds.  All other computers and devices in the House can stream video without problem.  Speed tests test our laptop Vaio 2009 to 16 Mbps download and 6 Mbit/s upload.  The Dell is the same download speed, but the download speed is 512 Kps!  It's like the beginning of the 1990s with telephone lines.  We called Dell a week ago and they told us to reload the driver for the wifi card.  The suggestion does not and we could not reload the driver and it made it unnecessary to the wireless card.  They sent us a new desktop case and put us together today and got the same results with slow download speed.  Need help with any suggestions that anyone has to correct the problem of download speed.

  We have a new Motorola modem and a new Linksys router.  And as I said, TVs, tablets and other computers work fine.  Maybe it's just a [Admin NOTE: expletives deleted according to the terms of USE] computer?  It's our first Dell and I must admit, we are more than disappointed so far.

• Very slow download speeds

  I just bought a macbook 12 "that I love. The only problem is I noticed very slow download speeds when downloading apps. I have also a 13 "macbook pro that I use on the same internet connection and downloads very quickly.  I have not tried to download any music or video yet, so I don't know if it's just a problem with applications, but it is ridiculously slow. It's a trait of these macbooks little, or something may be wrong?

• 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.

• 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.

• BlackBerry Smartphones very slow CPU speed.

  We have two BB bold 9900, we're working very well the other has very slow response to each action. even using the touchpad to navigate a huge delays. We also get the small icon of black clock all the time. There are many cases when the process is never ending and he must remove the batteery to reset the phone. Any thoughts? Thank you.

  A battery pull is always recommended to take the first step.  You have done this, then I would jump straight to a reload of the OS.  Why are we so slow 9900 and the other is not?  I really have no reason for that, but the reload of the operating system is a good step to take.  Not to worry even upgrade to a newer version, sometimes the same reload OS will do (update if a new version is available is however also recommended).

  To do this, connect your phone to your PC and open BlackBerry Desktop Software.  Click on the device at the top of the software, then click on restore.  Load the last restore point.

  Let us know if that helps you.

• OfficeJet 8720, scan to folder very slow network. any tips?

  I just upgraded to Officejet pro 8600 to 8720.

  The 8720 prints well, but it is incredibly slow for scanning.   Can't believe how slow it is compared to other HP products I've used.

  Is there advice, suggestions on how to speed up scanning?  Or do I need to buy a more expensive model for a faster sweep.

  Please notify.  Thank you.

  Hi @atomarchio,

  I was check in this issue and found a number of things that can help.

  Replace with the IP address of the computer that hosts the folder targets of network for the name of this computer.  For example, if the network path is listed as \\david\8670scans, change it to read \\192.168.1.102\8670scans.

  Turn on the printer and try again.

  Check out this post from @djjaeger82, Officejet Pro 8720 - slow Scan to network folder.

  Let me know how make you out. Thank you!

  ===========================================

  Think about it an absolute must - manually update your drivers.

  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: run DriverView - set
  SEE drivers to hide Microsoft - update those without drain in their names. (Also
  updated the BIOS and drivers from the chipset on the site of the constructor/the system motherboard).

  -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
  Poster: 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 Maker as replacements and system manufacturer of device which are
  the most recent. Control Panel - write - graphics card - device manager
  the brand and complete model of your video card - double click - tab of the driver-
  Note the version information. Now click on UPdate Driver (this can do nothing
  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 there are 3rd party with their own software and drivers and the other main device drivers
  you have.

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

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

  Always check in the Device Manager - drivers tab to be sure the version you are
  installation actually appears. This is because that some rollback of drivers before the
  later is installed (particularly that audio drivers) so install a driver - reboot.
  Make sure that it is installed and repeat if necessary.

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

  Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.
  http://pcsupport.about.com/od/driverssupport/HT/driverdlmfgr.htm

  Installation and update of drivers under Windows 7 (updated drivers manually using
  the above methods is preferable to ensure the latest drivers from the manufacturer of system
  and device manufacturers are located)
  http://www.SevenForums.com/tutorials/43216-installing-updating-drivers-7-a.html

  If you update the drivers manually, then it's a good idea to disable driver facilities
  in the updates of Windows, which leaves on Windows updates, but it will not be installed
  pilots who are generally older and cause problems. If updates provides a new
  driver then hide it (right click on it) and then go get new ones manually if
  you want.

  ===========================================

  Refer to these discussions because many more excellent advice however remember to check
  your antivirus, the main drivers and BIOS update programs and also to solve problems
  with the first method cleanboot.

  Hi JoshMayqa,

  A number of factors can affect the Internet connection speed. For more information, see

  Why is my Internet connection so slow?

  http://Windows.Microsoft.com/en-in/Windows7/why-is-my-Internet-connection-so-slow

  Note: Reset the Internet Explorer settings can reset security settings or privacy settings that you have added to the list of Trusted Sites. Reset the Internet Explorer settings can also reset parental control settings. We recommend that you note these sites before you use the reset Internet Explorer settings.

  Note: the data files that are infected must be cleaned only by removing the file completely, which means there is a risk of data loss.

  If issue persists I suggest you contact the Internet service provider for assistance on this issue.

  Let us know the status of the issue. If you need help, please after return. We will be happy to help you.
