IBM lotus Instant Messaging/Sametime tip concerning Hyper Threading

Category None
A simple tip really, if you want Sametime meetings to go active on your server and your server is a machine with Intel hyperthreading, turn it off. Otherwise you will see issues where schedulled meetings do not go active.

1 - Does this reduce performance as well or is hyperthreading anyway not supported ?

2 - Well I guess if it works versus not working the performance is better. This technote says it doesn't work and to turn it off, we had it on, and it doesn't work.

3 - Hi Carl, I'm told by IBM that this is not a problem with 6.5.1 can you confirm that it is ?

Many thanks..

6 - Do we know if Hyperthreading is still a problem on SameTime 7.0 and/or 7.5?
I am starting to think about a update from 6.5.1 and want to plan accordingly.

7 - I don't believe there is any change in this. I know I have seen the problem on Sametime 7.0 servers.
