Re: Intel Hyperthreading problem on server?

["Jason Lim" <maillist@jasonlim.com>]

Dear Gilles ,

I'll try as well... hope we can find a solution.

I have a few Redhat Linux 9 servers with Hyperthreading CPUs, and no
problem whatsoever. I think they run Apache 2, so maybe that is the
solution... but surely there must be people running Apache 1.x without any
problem and hyperthreading?!
