The T5140 presumably has two 8 core x 8 strand processors. On this box, a load average of 128 indicates that there is work for all of the CPU strands. That is, a T5140 with a load average of 128 has a saturated CPU, just like a Netra T1 with one UltraSPARC IIi processor has processor saturation when the load average is 1. Put another way, a load average of 20 means the processor is 15.6% utilized. Of course this is simplistic - you need to look at other factors, particularly corestat (use google). -- Mike Gerdts http://mgerdts.blogspot.com/ _______________________________________________ dtrace-discuss mailing list dtrace-discuss@opensolaris.org
