Hyperthreading - Word - Automation

[Nikolai Kirsebom]

We have a customer who has reported performance problems with new PC's
they are planning to use when they have enabled Hyperthreading. The
application they are running uses Word through Automation and they
experience severe performance problems when enabling Hyperthreading.
In this newsgroup on October 14th 2003, Tony Whyman posted an entry
describing a very similar problem, however noone ever replied to the
posting.

Does anyone know what might cause this, what to do or where to look
for help.

Thanks for any help.
