How does server load adverages work with dual processors?

[Joe Gronlund]

Its there two seperate values meaning eg:

CPU0 - .06 .03 .01
CPU1 - .08 .04 .00

or is the output different?

TIA :)

with redhat you just have the same value, however the ceiling is 1 x the number of CPUs.

Eg for a dual cpu system, 1.0 = 50% load.

Hope it helps

so adding another CPU wont affect the CPU load adverages , but i should divide them by 2 two get the real adverage?

so , 1.0 is really .5 ? :)

thanks

Yup, this is how redhat does things, not sure about other distros.

yup - it's the same for almost all *nix systems
