Re: configurations

Sharon,

Below is our activity report from last month.  This information is based
on data from the ADSM accounting log.  Note that this is aggregate data.
Rates for specific systems varies quite a bit, depending on what kind of
system it is, what type of network connection, disks, etc, etc.

Hope this is useful.

Notes:
  - Time      = total wall-clock time
  - MediaW    = % of wall-clock time spent waiting for Media
  - CommW     = % of wall-clock time spent waiting for Network
  - IdleW     = % of wall-clock time spent idle (waiting for user)
  - Xfer Rate = Transfer Rate (Bytes / (Time * (1 - (MediaW + IdleW))))
