[THIN] Re: Typing Latency

DNS appears to be configured properly with no issues....No NIC Teaming just
the single onboard NIC on the C Series HP Blade....The only packet handling
I am aware of is QOS that is defined for 1494 and 2298.....

Today I looked a bit at process explorer and I was seeing some really high
context switching numbers...Another thing that stood out was Symantec
Realtime scanning was still consuming resources even though real time
scanning is disabled for Citrix Servers via Enterprise Management Console.

I love these responses- they gives me a chuckle to know that we have all
seen the same things!

Well we are at our wits end with this one and looking for some advice...

First our background:

Windows 2003 Enterprise Server with SP2 - 32 BIT

Xenapp 4.0 with R04

Compaq C Series blades, Dual Quad Core Proc with 16 GB RAM, NICS are
attached GB connection

Clients are connecting with the newest Full PN ICA Client 10.2 through Web
Interface 4.5

We are experiencing typing delays and some random disconnects. Session
Reliability is kicking in from time to time with some session disconnects.
We have opened a case with Citrix and checked the normal stuff such as
Network QOS traces, perfmon traces, and speedscreen settings to no
avail..Clients are hard wired to the dual T1 network and the SMC traces
appear clean even while the issue is occurring..Norton AV is installed on
the workstations and Citrix Servers but real time scanning is disabled on
the Citrix Servers and a nightly scan is conducted at 2:00 AM..Servers are
rebooted weekly as well...

Any ideas?
