Hi
I'm not sure if that blockdev command helped or not...it didn't make things
worse, that is for sure. One thing that DID help quite a bit, was to edit
the Physical Interface (Interface Type) and reduce the Pings to Send from 50
to 0 which REALLY helped bring the load down. Thanks again. Looking into
the rrdtool 'beta'...trying to find it. Thanks
