Hello,

 

What version of XenServer are you running and how many VMs?  Did you
select the Optimize for XenApp under each VM?  What does you disk
subsystem and network look like?

Everyone,

 

After the applicaiton of all the below listed hotfixes and a number of
other MS hotfixes related to terminal services

we are still in a position of grief with these servers.

 

We are no longer experiencing a slow down or crash over time more what
we would call a significant slow down for the amount of users vs
hardware on the servers.

 

 

DL380 G6, 36GB of Physical Ram (34 available to windows)

Dual Intel Xeon 2.8, 16 Cores, x5560

Windows 2008 SP2

 

Problem

We are seeing server instability around 50 users, 45 seems to be the
limit.

With servers of such huge specs does any list legend have any further
ideas what we could be doing wrong?

 

 

Any suggesitons would be very much appreciated!!!!!

Thank s in advance for any assistance or even reading this 

 

Cheers

James

Quite a few of the below are not applied - have an action task to review
all and install requried and test after each one... thanks again Carl

There are a ton of hotfixes for Windows 2008 64-bit post SP2. Here's my
collection. All of these are related to TS in some way. Some of them
directly fix performance problems.
