Re: Updating system statistics

Results from 90 mins today:

  SREADTIM MREADTIM CPUSPEED MBRC ---------- ---------- ---------- ----------

      .571 .482 618 14

A bit of an improvement over the currently used stats, and the MBRC isn't too frightening.

I've set it up to gather for 6 hours tomorrow starting at 8 AM.

Thanks all for your help.

Don.
