In a whitepaper published by Brian Madden ("Terminal Server Performance Tuning") he states that:
"Whether you should enable Hyperthreading in a Terminal Server environment depends on
which operating system you’re using. At the time of this writing, enabling Hyperthreading on
Windows 2000 servers causes stability problems and actually decreases the overall performance
of the system."
The whitepaper is dated August 2003 and dealt with mostly Metaframe XP.
Just curious if anyone thinks this still (or ever did) have any merit. He doesn't go into a lot of detail as to why but I know he is quite the TS guru so I'm inclined to believe him. I do have some servers with hyperthreading enabled and don't know of any stability issues, but I was wondering about the performance.
