I'm running two DL360 G5 webservers each with two quad-core cpu's. Each have 8 GB of ram, one is 2 Ghz and the other is 2.33 Ghz. They run just fine. These two webservers have twice the weight of three opterons with two dual-core cpu's on our coyote load-balancer. The servers are so fast I had to adjust the read- and write-size in fstab for the nfs-mounts. Using 8kb I got the 'nfs server not responding - alive again' during peak on the new servers. Using a 2kb size instead solved my problem. They handle twice as much traffic as the 4-way-opterons. The quad-cores run 7.0 beta2 with ule, php, apache. -- regards Claus When lenity and cruelty play for a kingdom, the gentlest gamester is the soonest winner. Shakespeare
