    Default Lazy Swap!


    I have 933.4 MB swap memory. The only problem (is it problem? maybe.)
    that this 933.4 MB is free, always.
    Total memory (RAM): 883.6 MB
    Free memory: 11.4 MB (+ 379.8 MB Caches)
    Free swap: 933.4 MB
    -from sysinfo:/

    It has no function... Good to know before installing 11.1, how to
    partition my HDD. Is there any swap partition needed?

    It's very rare that I use any swap. But with 2GB main I have to
    thrashing the living daylights out of the box to get it to touch swap.
    Most of the memory should be cached with very little free showing. Which
    you seem to have.

    yes, you must have a swap partition....may not be used, but you must have
    it...'they' used to say you should have as much swap space as you have
    memory...I don't think that is still true...I guess 250 to 500 MB would be more
    than enough (but YOU check before you change yours)..

    I'm sure I read somewhere that it gets used if you have a laptop and use
    suspend mode, but I'm not too sure about that.

    Each time I tried suspend it either crashed, or in the case of "suspend
    to disk" took longer to restart than a normal boot!

    Not using swap is good. But since a GB or two of disk is nothing these
    days, it's also good to have some insurance. Really, unless you have a
    very small disk, you won't miss 1GB disk space.

    Okay, thanks for the suggestions I'll keep my swap partition.
    @growbag: Sometimes I need to suspend my laptop, so maybe it's used for
    something.

    Actually I believe swap is used when you hibernate.... not when you
    suspend. Suspending just means keeping RAM active and turning down
    other power-consumers... hibernate moves RAM to disk (swap) so you
    potentially need as much swap as you have RAM. Also swap is often
    better than running of memory. If you run out of memory things just
    don't start (including tools to help you free up RAM) where if you use
    swap you just get a performance hit. Never using swap is great, though.

    Good luck.
