Hi
Nice tool. I got mixed results when running it but the worst stats I could see
were
Last Latency (ms) 78
Average latency (ms)
69
Round trip deviation
7
Not sure if thats acceptable or what I can do to improve it...

J Well, if she doesn’t have EdgeSight, it’s the best tool to show you what’s
happening at the ICA level for individual sessions. It’s displayed there in the
GUI without having to explain anything. From: thin-bounce@xxxxxxxxxxxxx

lived! Get the ICA Session Monitoring and Control Console, or SMC Console for
short. It’s a free SDK Tool that works with most versions of Presentation
Server and XenApp. This will give you all the information about ICA Sessions in
a nice GUI. Cheers,Jeremy From: thin-bounce@xxxxxxxxxxxxx

performance counters you can setup easily in Performance Monitor. Look under
"ICA Session" category. It will give you actual ICA latency by session in

Subject: [THIN] Re: Citrix Farm performance over WAN Great question. Wish I
knew how to troubleshoot it. Our storage guy says there are no issues on the
NetApp NAS (Unix based I think) so I have to believe him. Ive run some perfmon
stats on my citrix server and have high readings for Redirector\Current Commands
Citrix Server
MaxMpxCt is set to 1024
MaxWork Items is set to 4096
NAS
CIFS MPX is set to 1124
Perfmon results
Redirector\Current Commands: Min 155, Max 246. Average 170
Server\Work Item Shortages: 0
Server Work Queues\Available Work Items: Min 30, Max 30, Average 30
Any suggestions on how to tweak server would be muchly appreciated
Regards

going to help. From: thin-bounce@xxxxxxxxxxxxx

Subject: [THIN] Citrix Farm performance over WAN Hi
We currently have 30 XenApp 5 Servers split between 2 Sites. Sites are
connected by Gig Links. At present we use Zone Preference and Failover and
Site A is Active only. Site B is for Disaster Recovery only. Site A is
running at around 75% utilisation according to Citrix Load Evaluator. As per
my previous emails we are having issues with SMB bottleneck. I am considering
removing Zone Pref and Failover and making Site B active also. Therefore all
XenApp servers get utilised which will half the resource requirements on my
servers and hopefully remove any bottlenecks.
Can anyone see an issue with running with such a config. XenApp Servers in
site B will need to cross the Gig link to connect to File Server/Web interface
but on a gig link I think should be OK. Any pro's/con's with this approach?
Thanks
