Do you (or anyone) know if these multithreaded benefits are spcific to
Redhat or some aspect of the kernel they are using. I've just downloaded
Mandrake 9.0 which is using the 2.4.19 kernel and wondered if these
changes would be seen here (I'll have a dig around myself but thought
I'd ask in case the answers already known).
Thanks
Steve
