Hi Mike, I guess you mean just listing the file in a command window, that's actually pretty cpu intensive because the "DOS" window has no smart font handling capabilities. It doesn't use windows APIs or anything, just displays bitmaps. Try something simple. On your local machine: c: cd \ dir /s > dirs.txt (now start the task manager) type dirs.txt (watch the CPU utilization go to 100% while the text is scrolling in the DOS window) And that's local. The ICA client is limited in what it can do about handling a scrolling bitmap so the end result is the same. Since the video virtual channel is basically running at a higher prioroty than anything else, keyboard and mouse input is backgrounded (ie doesn't respond in a timely fashion) while the bitmap scrolling is going on. Just get your users to use a text editor. While notepad is pretty darn stupid (especially when doing a global search and replace on a large file), there are freeware editors around like "TheGun (Grown Up Notepad)" which do a pretty good job. regards, Rick Ulrich Mack Volante Systems ________________________________ From: thin-bounce@xxxxxxxxxxxxx on behalf of Pedigo Michael-G17060 Sent: Wed 8/09/2004 5:34 AM To: 'thin@xxxxxxxxxxxxx' Subject: [THIN] High CPU at the end client when using published apps from MPS 3.0 Hi, Has anybody else seen this??? When running a simple command window and cat the file (60K text file).....CPU on the client will max out at 100% All MPS 3.0 servers does this (3).... If a user is running multiple applications they start freezing and general performance stinks..... Can anybody else reproduce this? I can run the same apps and cat the same file on my Metaframe XP farm and I can see CPU shoot up, but it appears it is correctly managed and never consumes 100% and it runs much faster on 550MHz processors vs 3.0GHz Any advice or at least acknowledgement others can or can't see this issue would be greatly appreciated.
