Hi Mike,

re:

Looks good.

re:

So, something happened wrt the SJSU network since we started this
investigation.  I believe that the change happened last week when
the indicated latencies on vulcan went from very low to a pronounced
climb towards 3600s.

The real-time stats plots of latencies (not from rtstats, but from a
test system that is powered by Daryl Herzmann's implementation) look 
terrible - the latencies are like pegged at the maximum value.  It
will be very interesting if the latencies go back towards zero
after the end of the normal school day!

Excellent!

re:

It should help with the large Full Disk images from the SATELLITE feed
being inserted into and processed out of the queue.  This should happen
after the latencies drop down to values that are less than the maximum
latency value that is specified in the LDM registry.

Cheers,

Tom
