Hi Steve,

OK. Quick comment: the '*' after 'gfs' is not needed. The following
REQUEST will do the same thing and be more efficient:
REQUEST CONDUIT "gfs" idd.unidata.ucar.edu
re:

By maximizing, I assume you mean that you want to be processing
all of the GFS data that is being received. True?
re:
> I found that we are pulling 5.0GB.hr - same as a few days ago

OK.
re:

No. The reason to split the feed REQUEST into multiple, non-overlapping
REQUESTs is to decrease latencies, not to increase the volume of data
that is being REQUESTed.
If your machine is rfd.atmos.colostate.edu, then I can say that the
CONDUIT latencies you are experiencing are good (meaning low):

The latencies in your CONDUIT reception look good:

This means that you do not need to split your single REQUEST into multiple,
non-overlapping
REQUESTs.

You may or may not need to split your REQUEST if/when the 0.25 degree data is
added
to CONDUIT; the CONDUIT latency plot will show if splitting is warranted.
re:
> Thanks again!
No worries.
Cheers,
Tom
