Both CPUs were definitely in use; since these are Xeons with HyperThreading, there's effectively 4 logical CPUs for the OS to use. The OS sees them all; if I only put one to use then top (over time) shows just 25% CPU in use which is correct. I generally run super-smack with 4 or 5 clients to exploit the entire CPUs. The super-smack results scaled roughly linearly up to 4 clients and then held fairly static as the number of clients grew beyond that, so I'm fairly sure all the CPUs are being used - just not as well as they should be. I didn't record firm numbers, I'd have get FreeBSD back on to get some firm results for that. -- Chris -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
