  • Between php5 and MySQL they eat memory and swap

    Hi!

    I have a debian lenny running on a little 512ram 64x personal system, everything was running smoothly until recently. I have a couple of blogs and some friends blogs running, DB are less than 20MB. And the mangos DB about 130MB.

    Heres my performance:

    Output from TOP command:
    SWAP DATA COMMAND
    233m 46m php5-cgi
    199m 194m mysqld

    #vmstat 5 2

    procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu----

    I guess since today is sunday performance its ok, but I can get swap filled up to 70% and i/o waits up to 100% for 15 or more seconds.

    Can I get a little help to get the swap use i/o waits down?

    thanks!
