In a world where CPU's were slow enough that even /bin/ls was a CPU bound task because it sorted the list, loadavg is a good indicator of how much the CPU is doing. These days man processes, in particular network servers, never use a full quantum and therefore the load-average can vastly overestimate "how much the system has to do". The thing to remember is that the loadaverage indicates how many processes would like the CPU, not what or how much they would use it for once they get access to it. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk_at_FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.Received on Mon Feb 21 2005 - 13:20:37 UTC
