Tom, At the moment we are using the old servers but will be replacing them later this year. We are currently looking into virtualisation for the new servers so we are still to make decisions on hardware for them. There is one new server in the new farm to help with the change over. I have been removing one server at a time from the old farm and then rebuilding it to the new specs before moving the next bunch of users across. My problem with this is that I'm going to run out of servers due the extra resource usage in the new farm!! Our old servers are all dual processor Dell's with 2/4GB RAM. I surmise by your comments that you also didn't receive the improvements as promised by the resellers. Thanks for your feedback, Geoff. -----Original Message----- From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Tom Flanagan Sent: Friday, 28 April 2006 13:30 To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: Memory Usage Hi Geoff Post upgrade blues eh?....promises not delivered. Results and performance improvements hardly recognisable. I know the feeling. What hardware are you running(processors etc). did new servers go in with the upgrade? Your previous farm must have been a few years old? I can't give you any suggestions on optimising memory usage. Explorer looks hig compare to my environment ps4 w2k3 these are my averages for the processes you mention explorer 9MB wfshell 4.5 - 6mb crss 4mb winlogon 4mb Regards Tom Flanagan IT Manager Doric Constructions Ph: 08 9388 2655 Mb: 0408 927 247 -----Original Message----- From: Geoff Cridland [mailto:geoffc@xxxxxxxxxx] Sent: Friday, 28 April 2006 11:06 To: thin@xxxxxxxxxxxxx Subject: [THIN] Memory Usage Hi All, We have been running a small Citrix farm with Windows 2000 SP3 and Metaframe XP FR3. Finally we are making the conversion to Windows 2003 SP1 and Presentation Server 4.0. After hearing all of the hype from both Microsoft and Citrix about their relevant upgrades being able to increase the number of users we should be able to now get on each server I was looking forward to the change. However, to say I am disappointed with the memory usage results of the upgrade is an understatement. I now find that I am not even getting as many users on each server let alone an increase of 25% or more as stated by some sources. We are running the same applications (including versions) on the new setup as we were previously. I have turned on memory optimization which may have made a little improvement to the applications, but the problem seems to be related to the new operating system and the new version of Citrix themselves not the applications. On an old server I would get 40 users consuming only 2.5 GB RAM, but on the new servers I get only 30 users and I'm already consuming more than 3 GB RAM. It appears that the main consumers of all the RAM are operating system/Citrix process rather than the applications. For example, on the old server Explorer.exe consumes around 5MB and on the new version around 15MB. Crss.exe was 2MB and is now 5MB, winlogon.exe was 3MB and is now 6MB, wfshell was 3MB and is now 5.5MB, This e-mail and any file transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
