Hi Guys, We've got a XenApp 6 setup that we are running here at work for around 80+ users, and we are having performance dramas. Many users are complaining about the speed of the system. I've been looking into what is causing the issues but so far all I can work out is that the XA servers are overloaded. Setup: * XenApp 6 * 7 XA Virtual Servers, 2008R2 SP1, running 2vCPU's, 8GB RAM, 40GB disks with profiles and 99% of data stored on file server(s). * Wyse C90LEW thin clients * 4 XenServer 6 hosts, 2x 64GB and 8 CPU's (E7340's), 1x 48GB and 8 CPU's (E7340's), 1x 48GB and 16 CPU's (E5345's) I guess I'm just looking for what I should be looking for or ways to test what is actually causing the issues. It has always been an issue, we run the following software: Lotus Notes 8.5.1 Basic Office 2010 Internet Explorer TRIM (although we haven't yet gone Live) our main LOB app is through IE8, which 70% of staff always have open.
