We have a citrix storefront version 2.5 We have more than 15 stores created, When users started using the url upto 5 the performance is good. When more users started using their url the performance very very slow. In storefront server itself too slow when we mange the stores. Need help to fix the issue.

How many apps are the users subscribed to?
15 seems like a *lot* of stores, is there any way to consolidate them?

Check the performance of your StoreFront server and your XML servers on the other end.. see which end you are getting hammered on.

Also, you can *very* easily bring up more StoreFront server and join them to the group.  At that point, you just need a load balancer to be the front end.

Nope not possible as all the stores are used by different anonymous  users and performance on server is less than 50%. Is there any other options to fix the slowness, In web interface its working fine.

How can I check performance issue between storefront and xml servers.

I meant check the CPU/Disk etc, on each side StoreFront & XML server,.

But if I remember correctly, the stores are queried sequentially, and I don't think there's much you can do to speed it up :-\

if you need many time to call the store properties, the XenApp/xendesktop XML services should not be the bottleneck.
which type of SQL server do you use? SQL-express uses restricted hardware-ressources.
Check with taskmanager which proccess uses the most CPU. Sometimes 25% CPU load at a 4 CPU-System means 1 CPU with full load.
Also check with Windows resource-monitor your network-connections and Network Latency.

Check with "netstat -n 5" if you have TCP-connections with "SYN" state.

if the user connects a second time (or you open the GUI a second time) is it more fast?
