If I have a quad core server, should top's load average show four values?

    Hello

    I hope someone can help me with this.

    I have a quad core server. The first five lines of 'top' looks like this -

    [PHP]
    top - 21:21:02 up 169 days, 9:22, 4 users, load average: 0.20, 0.38, 0.41
    Tasks: 127 total, 1 running, 126 sleeping, 0 stopped, 0 zombie
    Cpu(s): 0.0% us, 0.1% sy, 0.0% ni, 99.3% id, 0.6% wa, 0.0% hi, 0.0% si
    Mem: 2074696k total, 1944636k used, 130060k free, 404968k buffers
    Swap: 2040212k total, 45640k used, 1994572k free, 948364k cached
    [/PHP]

    The load average on the first line only shows three values. Should it show four?

    Any help appreciated.

    Thanks!

    No, that's correct.

    "The three load-average values in the first line of top output are the 1-minute, 5-minute and 15-minute average"

    Hmmm - 2Gb's memory & quad-core?
    You're bottlenecking at the memory.

    I'd flog two cores and double the memory! :)

    That's not a bad idea. I will look into it. (Doubling the memory, not losing two cores!)

    Cheers!

    you can always tell top to show the individual loads on each processor by typing the character '1' as it's running.
