VMview 5 and performance issues

Hi all,

For the past couple of months, a couple of individuals in my office have been complaining about performance issues when it comes to using vmview and pcoip.  This morning I was notified of yet another instance where the session went to a black screen and disconnected.  In googling this, I've analyzed the log files and used the PCOIP Log Viewer and have not observed any spikes in bandwidth or latency issues.  This same group of people explains that they do not have this issue when the work from home (making me believe that it's purely a network issue).  Their view template has been tweaked to allow 4 Gb's of ram which solved some of the issue, but not all of it.  I do not observe these issues; however, I'm in a different part of the building.  Does anyone have any suggestions on how to begin diagnosing this?  How can I determine if it's more of a bandwidth problem with hardware or not?  Any help would be great.  

Thanks.

No issues from home via low bandwidth, only from within the office?

are they in the same building, off the same switch?

Yep, only from within the office.  And yes they ae in the same building and on the same switch.

just these users on this switch and building?

any other users in the same building, on the same switch with issues?

I would start checking physical swithces, networking

It's a majority of these users and yes they are on the same switch.  However there are some people not on that switch that are observing the same issues.

so what is different about the connection from home?

does it terminate on different switches, bandwidth from home has got to be less?

have you seen the issue first hand?

The difference about the connection from home is that it's not going through the same switches.  In the office, because they are on the other side of the building they have their own switch that they are connecting through before they hit the backbone.  At home they are jut going straight to the backbone.  

I have seen the issue.  Everything seems to be working fine and then all of sudden everything just gets very slow, freezes, and gets stuck.  It will either then never recover or it will just turn to  black screen.

The answer must like, with your network infrastructure, as you ESXi installation must be sound, as both home users and network users would have the same issue.

I would start looking at logs on the edge switches, look at performance counters, do you have any network monitoring?

I've actually been looking at the logs.  I have one individual that I'm looking at specifically because I can see the spikes on her graphs for bandwidth utilization, rate limiting, connection quality, and packet counts.

Is there any other type of monitoring you would suggest?

Also, the individuals have the problems are running Windows 7, 32 bit.  Does that pose a problem?  I have noticed that if we allocated more than 3Gb's of memory that system will only allow for 3gb's to be used.  

I wasn't here when this environment was setup, so I don't know the reasoning for the no 64 bit environment...

1 Ensure that enough network resources are available here

2 Confirm that you have allocated sufficient hardware resources to the virtual desktop here

3 Ensure that the network is optimally configured for VMware View virtual desktops here

4 Confirm that no third-party issues with the guest operating system in the virtual desktop exist here

5 if the above steps doesnt fix the problem you can Collect the VMware View diagnostic bundle follow this link

Rs, we are currently in the process of running new home runs to these selected individuals that are having a problem.  I'll let you know what comes out of this.
