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

bottleneck” if its “back end file server” its unlikely this configuration is 
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
Ang
