Citrix - How can I speed it up

By California Dead Head ·
My users are complaining that CITRIX is slow. I noticed that when I log on to the internet like now or at hotmail I can type as fast as I want and there is very little lag. However, sometime when I am logged onto the Citrix server with the same connection it is slow and can't keep up with my typing. Outlook takes a long time to open. I have a new Dell server with multiple CPU's and a whole lotta RAM 1.5 GB. The performance monitor on the server show the CPU usage is low overall. My clients are on DSL lines coming into a T1 line at the main office. Virus software is off on both. What are some things to do that will enhance the speed of Citrix???

Thanks for the info

Citrix - How can I speed it up

First, how many clients are you supporting? Everything filters through your T1, including, presumably, internet activity at your home office. You might look at the volume of traffic flowing through the router.

While 1.5 gb may seem like a lot of memory, check for the Citrix recomendation versus your number of users.

Speaking of the router, make sure it can keep up with the T1. (Some of the cheapie routers cannot really handle the full flow.)

While it seems that you have everything fast, check the traceroute times from each of your clients to your server. It may be that your DSL vendor(s) and your T1 vendor do not have private peering and the connections are actually slow in the middle. (I had this once with a big client -- T1 on one side, T3 on the other side, and about 250 bytes/sec through the peering point.)

On the server itself, make sure you have the server type optomized for server, not local applications (system properties/performance).

If you are using a screensaver on your server, make sure it is nothing more complex than blank screen. (The really nasty one is 3D pipes, which will slow your server to a crawl.)

How fast are you accessing disks? Use the performance monitor to monitor disk activity for awhile to see if the disks are the bottleneck.

Is your server set for enough disk cache? Use the performance monitor to watch disk activity and cache hits. Remember that too much cache can also slow you down by eating too much memory.

Check theEthernet connection to your server. If you are on a half-duplex 10mb connection to your mail server, running Outlook for many users, this can slow you down also. (This addresses the slow Outlook issue rather than the slow typing issue.)

Good luck.

Citrix - How can I speed it up

by WanabeDrSean In reply to Citrix - How can I speed ...

a t1 is only 1.4 mb p/s wich seems fast to am few users but if being hammered on by citrix clients can slow down I have seen 1 instance where a system engineer had a metaframe server that he kept adding processors to as his number of users kept doubleing he got all four processors in and said the server was slow but he never loaded the multithreded kernal and so the other three cpu's have wer3e not being used.
good luck
