  • so?

    I/O isn't amazing, I wonder what HDDs are in the node? I'm sure since it's new people are installing OSes and applications, so it's expected for I/O to be bad. You should update this in a few days.

  • Memory usage is a lil bit strange.
    This is on fresh installed Debian 6 32bit using maxexcloo minimal script, and Apache 2.4 running (without PHP & MySQL):

    As for disk I/O I totally agree with @Kairus, try again in a few days and we should get a better score for benchmark.

  • @NanoG6, Memory usage looks normal... you have 223mb of free RAM in your cache.

  • Ah yes you're right
