EvanI am having the same issues in regards to keystroke delays and intermittent hanging in sessions. I have enabled Memory optimization to see if that makes a difference. Will keep you informed. Failing this I will look at Appsense

I have very high virtual memory usage, even though I have 1 to 2 gigs of physical memory free. I also have plenty of idle CPU but I have heavy complaints of a slow user experience, such as Outlook keystrokes not appearing as they are typed. I have plenty of bandwidth (10mbits upstream with only 3mbps used), and the users complaining have plenty of up/down bandwidth available. Could high virtual memory and paging cause this type of performance problems, or would it be unrelated? ________________________________ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Rick Mack Sent: Wednesday, January 03, 2007 6:56 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: Controlling Virtual Memory Usage Hi Angela, Sounds like a Java app :-( Seriously, DLL remapping (memory optimization) probably won't give you a lot of value in your scenario, but it'd be worth trying. Sure there's the risk it will break something but it's dead easy to turn off without rebooting to check. And there's enough tweaking possible to have memory optimization and everything working as well. However a product like Appsense performance manager that also does memory working set trimming of backgrounded and idle processes will probably work much better in your scenario. Try the eval version, or better yet get your reseller to install an eval version and see how it goes. It's not cheap but it's also a lot less expensive than more servers. Considering that paging activity is likely to be the bottleneck regardless of the size of the pagfile(s), I'd suggest you stick with the configuration you've got and try memory optimization and Appsense first. It's possible to have multiple page files on separate partitions or even the same partition but it'd probably make things worse for you rather than better. regards, Rick Ulrich Mack Commander Australia On 1/3/07, Angela Smith <angela_smith9@xxxxxxxxxxx> wrote: Hi Almost all my Windows 2003 STD / Presentation Server 4 servers are running out of Swap space. Hardware config is: Dual 3.6Ghz 4Gb RAM Swap size is 4095 - 4095 and it resides on the C: Drive. Main process which is using most of the Swap is Internet Explorer. Most of our Published apps are browser based so I have numerous IEXPLORE.EXE processes eating all the swap. Alot of the IEXPLORE.EXE processes use between 150Mb - 300Mb of VM. Is there any way I can tweak the memory usage for IE to minimise the amount of Swap being used? We have not enabled memory optimization in Citrix farm properties as I read it breaks certain applications? Is this the case? Will enabling this assist in this issue? I was going to purchase extra servers to lighten the load but most other resource indicators are OK. I would prefer to tweak existing servers if possible. We have between 80 - 100 sessions per server (40 - 50 users per box on average) Any suggestions appreciated Thanks Angela
