AMD64x2 vs Intel: which`s better for bzip?
Hi all.
Please, give me an advice: which processor is better for linux? I have to setup a server which will be loaded with 'bzip'. Is there some tests for modern linux distros? I`ve googled for `em, but I was unable to find something useful. In other words: what is better for bzip - CPU frequency or multi-threading?
Thanks in advance.

Bzip is not multi-threaded, to the best of my knowledgge. Consequently the number of processors should not make a difference to it's operation.
Technologically, among dual core processors, the AMD64 X2 processors are, at present, significantly better than Intel's dual core offerings.

Neither. CPU frequency is not linearly related to a processors prowess for arithmematic / FPU calculations (as is seen with AMD's processors). And multi-threading is useless if the application is not multi-threaded.

Thanks, vinu. So there`s no difference between these processors for bzip?

I would say that it would not matter or would have no accurate fact which one is better for bzip. Intel and AMD both have their pro's and con's.

Ofcourse if your server is issueing alot of bzips, you could try to configure it so that it will run 2 at a time. Then it could benefit from an X2.

Or if your running bzip on very large files you could make bzip exclusive to one core, thus leaving the system still responsive.

Hmm...it makes sense..I`m using FC4 too. Do you know how to bind a process to specific core? Please ).

U say it's a server, so if there is a chance of people logging in at the same time and running bzip then you'll get an advantage from dual core for sure.
