If you are running a SMP enabled kernel, you should be fine. What does cat /proc/cpuinfo tell you? If you have two quad-core xeons, you should be seeing 8 processors in all there.

I have Xeon Quad core processor server. And I have attached one more same processor to that motherboard. So now I have two processors on one motherboard. I have already installed Fedora Core4 on that. But after attaching new processor instead of getting fast its getting slow. Specially when samba user connects samba share or nfs clients connect nfs share it takes 2-3 or more for them.

FC4 is quite old. Try upgrading to F8.

It doesn't matter. Linux kernel supports multiprocessor from long time (some Google hits gave results with kernel 2.0.37 days).

So, check that: cat /proc/cpuinfo shows two (or more in your case..) processors. If not, something must be wrong with kernel, or you may need to recompile kernel or at last, you need to use FC8 :P
