Thanks Peter and thanks to all for the information. It turns out that the several HP Proliant DL380G5 the company is about to buy, will run SQL Server 2000, RHEL 5 w/Tomcat and Exchange 2003. So it seems that after reading several documents linked here and on the net, Two Xeon Quad Core at a little lower speed will be more efficient that 4 Dual Core Xeons at a little higher speed. And not to mention the benefit of using only two sockets instead of four. So, I guess i'll go for quad cores. If anyone is interested in benchmarks, please let me know offline at : eaperezh ((at)) gmail ((dot)) com Thanks, -- ------------------------------------------------------------ Erick Perez ------------------------------------------------------------ _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
