Jeff Marshall recently pointed out that archiving latencies had
been rising again - to at least several hours and occasionally
the good part of a day. So I pulled out the programming hammer
and stated whacking off milliseconds here and there - eventually
it starts to add up. I'd guess I probably convinced the system to
process about 30% faster overall.  It's hard to measure because
processing gracefully switches towards a more efficient batch mode
when dealing with large backlogs.

Today I saw the backlog almost clear - not quite but close. It was witin
40 messages at one point. That would have been fun as the backlog
hasn't hit zero for about 6 million messages. Maybe we'll get there
next week, or maybe traffic will grow again and take back these
gains. In any case, expect lower (but not zero) archiving latencies
at least for a while.And I'm happy to not fret about replacing hardware
for a change.

Jeff
