Prolasso looks interesting. As Joe pointed out, the Citirx CPU optimization is based on Aurema technology. It's approach is to carve out a certain amount of CPU for the system itself and then assign ceilings for user processes. If a user is assigned, let's say 10% of available resources, they can use more when there is no contention but when the system is loaded it will always reserve that much for this user. This is a great approach because the user always gets the benefit of available cycles when they are unused by others but is also guaranteed a minimum level of availability when the system is loaded down. The version that was been included in PS Enterprise edition is not configurable. So I assume that it applies this basic algorithm to all users equally, it seems to work well and if nothing else it avoids the situation was form the old days when something really stupid, like a dialog box, can peg the CPU for everyone...

That used to be what AppSense did. Citrix's technology is based off the Aurema 2.0 product (they have since acquired the company) which was fair-share. The 3.0 version was much more advanced but I'm not sure what Citrix's plans are with it.

Best wishes to all in 2008. I forgot to post this before Christmas (and havent had time to test due to wifey insisting on work free Xmas ) http://www.bitsum.com/prolasso.shtml I havent tested it yet but it certainly looks interesting. It does some things similar to AppSense Performance Manager and looks like it does much more than Citrix's built in CPU clamping. Matt
