That's pretty much what you would expect. Essentially any x64 cpu will be way faster than a T5120. If you're interested in straight speed, then the x64 is a much better choice. If you have a workload where you expect to be doing massive amounts of work in parallel, then the T5120 can give better throughput (although current Intel and AMD cpus can beat a T5120 in throughput as well, as the T5120 is a pretty old box now). -- -Peter Tribble http://www.petertribble.co.uk/ - http://ptribble.blogspot.com/ _______________________________________________ perf-discuss mailing list perf-discuss@opensolaris.org
