There's a reason for that. Dynix divides the load average by the number of CPUs you have. If uptime(1) displays 1.6, and you have four CPUs, then the load average is really 6.4. If uptime(1) says "1.6" on a 4-CPU system, the load would really be 6.4 *on a single processor system* If Dynix says the load is 1.6, it really is 1.6 . The load average is very relative to the machine you're working on, though. System Memory # users 'load average' Delay in response time 20-CPU Balance 21K 22 Meg 50+ 0.8 none VAX 11/750 8 Meg 28 37.69 minutes per keystroke MV/15000 (~12 Mips) 16 Meg 1 15+ none Load averages can be very misleading, and should be looked at with respect to the load average _on the same system_ under varying conditions. It is "the average number of jobs in the run queue over the last 1, 5 and 15 minutes", nothing more.
