Centos 3.5 64bit vs Centos 4.1 64bit defferent results!
I am testing Centos 3.4 64bit and Centos 4.1 64bit on the same server and I am getting very different results. The server is a AMD athlon 64 +2800 with 1 gig of ram and a 80gig SATA 150 hard drive. If you look at the Pipe Throughput they are very different and I havent made any changes in the bios. Do you know what could be wrong? Here are the bench marks.
