[THIN] Re: Typing Latency

We ran  into the same thing with the network latency between the client and the 
servers being less than 200 ms (avg about 150 ms). A network sniff revealed 
that mouse movements packets (about 8 to 11 bytes per packet) were overloading 
a cisco switch and router (older version of IOS and hardware) as there were 
about 1000 per second from each user. 
On the cisco switch we noticed buffer overflow errors and open a case with 
Cisco where of course they stated " this is a known issue with that version of 
IOS and model number". We are replacing the equipment ("in due time " says 
mgmt) in the mean time we enabled max compressoin and mouse queing which seems 
to resolve the issue until the equipment gets replaced.

I will have to check on spanning tree with the network guys...This app does not 
use Office.....I read through the article and we have done those things ....

 

Any other ideas?

Do you have spanning tree disabled on the router? If not disable it.  Are you 
using office?  Have you disabled the language bar for word?

Have you read through the article here ?

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?
