High load on Windows 2003 Terminal Server
Nov 11, 2009 Server Virtualization, Work
All this past week we have had extremely high CPU usage on our main Microsoft Windows 2003 R2 x64 Terminal Server. This server has 4 CPU cores assigned to it and 16GB of RAM allocated to it on our VMware ESX 3.5 host. This server averages about 60 users logged in at any given time throughout the day and maxes out at a little over 100 users logged in on occasion. After doing a lot of searching all over the internet for a solution to fix the problems I ran across: Virtual machine CPU usage spikes and remains abnormally high after VMotion in a VMware DRS enabled cluster. After my boss got back from being on vacation due to his wife having a baby we finally were able to update VirtualCenter 2.5.0 to Update 5. This has improved our issues but has not resolved them totally. Next thing to do is setup a Terminal Server cluster to share the load between multiple virtual servers in our 2 ESX server setup.
