Slow network performance for non - vm with ESXi 4.0 machines

• 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...

• 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.

• ThinApped Firefox 11 slow network performance

  Hi all

  We have thinapped firefox 11 with thinapp version 4.7. However, we have serious network performance problems when using firefox. In the thinapp firefox on speedtest.net, we get 1000ms ping ~10mb/s download and 3 MB/s in upload.

  On the native IE9, we get 100 ms ping ~95mb/s 39 MB/s in upload and download.

  At first I thought it was a sandbox problem, as we have our sandbox in %APPDATA%\microsoft\windows\sendto that is redirected to a network drive. I changed this option to use the current directory of the thinapp, but this made no difference. I also tried to add the "DisableRegistryTransaction = 1" option, but it also made no difference.

  The ThinApp was captured on a clean XP VM and I test it on our version of W7. I tried this on our XP build legacy and receive the same results.

  Does anyone else have this problem? And are there any suggestions? For the moment, we are looking to put firefox in our basic build or delivery through SCCM.

• Workstation 9 - slow network performance between the host and guest

  I am running windows 8 on the host and installed by 9 trial. Then installed windows 8.1 as a comment system.

  I'm a slow, very slow network between the two.

  If I send files to and from the computer with another guest, transfers are normal, but if I try the same files between the host and the guest, they are really slow.

  I use a bridge connection.

  I read elseware to disable the following on the guest card:

  Large Send Offload v2 (IPv4)

  Large Send Offload v2 (IPv6)

  But that did not help.

  Thoughts?

  Maybe then try Hyper-v, it help you better.

• x 220 slow network performance

  I have a x 220 windows 7 32 bit and with cable and wireless I get extremely slow performance. The chip is an Intel 81579LM and copy files over the network via the cable network for example I get only 800 Kbps. If I plug my desktop PC into the same switch I get something much faster. So the problem is definitely on the 220 x. I tried various driver updates, but nothing seems to fix. I ran perfmon and CPU and disk read/write queues are not a problem. Where should I go from here?

  .

  You use the same Ethernet cable between the device and the same port on the switch for the two tests?

  If this is not the case, try to do the test with the help of two Ethernet cables between the devices and the same port of the switch... This would pretty quickly sort if you have an Ethernet wiring related issue - it's pretty common root cause of the problem you describe.

  See you soon,.

• How do I apply the network drivers for CD when installing ESXi 5.0?

  I am completely new to ESXi. I was not able to find the installation instructions, but they have to be there.

  Anyway, I burned the isos of ESXi 5.0 rollup and driver on CD. ESXi enters the installation and then stops with the message on the NICs 'without cards network have been detected. No network adapters are physically connected to the system, or a driver not been located. A third-party driver may be required. I expected to have the ability to point to the cd with the drivers rollup cd, but the only option is to restart. How should I proceed?

  drivers must be in the ESXi installation media.  You can use the generator image and PowerCLI as indicated below.  Same steps apply

• Slow network performance

  Hello. Since version 6.4.0 I have very slow write speed. Now I launch last 6.4.2 RC1 and I have the same problems. My antivirus is disabled because I bought my readynas. While I can copy ReadyNAS with speed 20-30mbps under gigabit lan when I try to write something via lan I get 5-7mbps speed. Is there a solution? I must say that before 6.4.0 version I've had close read and 70mbps write speeds!

  Try without regrouping and see if the behavior changes.

• Advice of external storage for use with ESXi 3.5 (free)

  I'm under ESXi 3.5 (free) on a server with internal storage.  I would buy external storage and switch my VM to it.  The virtual machines that I have running on the server are not used very often, so I don't want to put a lot in it.  Can anyone recommend an external SAN/NAS storage device that would work with ESXi 3.5 (free)?  I'm looking for maybe 500 GB - 1 TB connected to the network via Ethernet.

  Less than the price of Iomega devices (the ~ $300 model) are sold to a group of work so not really high performance. If you find that this performance was not acceptable, you'd have no way to improve the system.

  I would like to use your existing NAS NFS features. If this does not work out, you can always go for something with more umph.

  If it is a lab test the Iomega should be fine. If it has an environment that can grow in size requirements and performance over time, you might want to try to build a more powerful Openfiler SAN/NAS.

  First try your existing infrastructure.

• How to monitor the TX and RX on PERFORMANCE for virtual network adapter BASP monitor?

  How to monitor the TX and RX on PERFORMANCE for virtual network adapter BASP monitor?

  I have a virtual network adapter that is created with Broadcom.

  This virtual interface named "BASP eCard" visible on the performance monitor in the category 'Rhythm Pipe' but not in the category "Network Interface".

  This is problematic because the Tx and Rx (bytes received/send in second) is available in "Network Interface" that show physical network cards only.

  Someone has an idea?

  Thank you

  This issue is beyond the scope of this site (for consumers) and to be sure, you get the best (and fastest) reply, we have to ask either on Technet (for IT Pro) or MSDN (for developers)

• Having problems with ESXi/vSphere Client Network

  First of all, I apologize if it's thread is in the wrong section.

  I recently installed ESXi v6.0.0 in VMware Workstation 12.0 trying to familiarize myself with ESXi as I recently graduated and I forgot most of what I learned from the class I took.

  Then, ESXi installed smoothly and was very painless.

  Then, I tried to create a virtual machine. It's when things are messy. I can't understand why, but I don't get any network connectivity after obtaining a DHCP address to all within the virtual machine, in addition to being able to ping the host ESXi itself.

  First of all, networking is like so:

  10.10.10.1 router/gateway

  10.10.10.254 DHCP, DNS, server, VMware Workstation files 12

  10.10.10.250 ESXi host

  10.10.10.244 ESXi reviews - Windows 7

  Googles DNS 8.8.8.8

  VMware workstation 12:

  AMD FX-8350

  Intel Corporation 82574L Gigabit Network Connection

  NVIDIA Corporation GF119 [GeForce GT 520] (rev a1) - However, not allowed to work with VMware VMware or xvnc throws a fit to this topic

  ESXi host

  Images: 2015-10-04_21-13 - 57.png, 2015-10-04_21-14 - 34.png

  The vSwitch has the following properties:

  Image: 2015-10-04_21-19 - 38.png

  
  

  And the following then occurs on the ESXi prompt:

  Images:,2015-10-04_21-01 - 58.png, 2015-10-04_21-03 - 32.png

  
  

  I can't really understand what the problem is, or what is happening. Yes, I could set up an internal network of the virtual machine with a firewall and what not, but I was hoping that there would already network connectivity while I wouldn't do. Also, is it possible to make attachments online?

  
  

  Thanks for all their help
  

  This could be a problem of permission on the host vmnet adapter, see http://kb.vmware.com/kb/287.

• Put network advise for new installation ESXi

  OK please bare with me as I'm still new in the world of "vmware". I am about to install our new server vm infrastructure and hoped some advice and guidance to make sure I understand the first time...

  I have two physical hosts with a new ESXi 4.1 installation. Each host has six physical gigabit NIC that I plan on the use of iSCSI and vmotion. I have also two HP without HP gigabit switches and two. On each host, I intend to configure the following networking:

  vSwitch0
  -the vm network

  -service console

  vswitch1
  -iscsi

  vswitch2

  -vmotion

  Each vswitch will have two physical cards for purposes of Multipathing (one network adapter for each HP switch). HP switches are not stacked as I like to keep independent and to avoid any downtime if a switch fails. Also, the HP without having two network cards and will be attached to each of the HP switches. I have two Setup VLANS on switches HP, the first vlan is part of my regular business network and the other is just for traffic iscis/vmotion.

  Before going any further... does that make sense and its sensitive so far?

  Hello and welcome to the forums.

  I would follow the advice of Edward Haletky in "gears Blue - 6 NIC with VMware ESX physical."

  Good luck!
