I ran a bunch of tests back when 6.0 came out, and the differences that we saw from bdb spooling and other changes (threading, I'm sure) were quite impressive.  With v5.3, we couldn't have more than about 12k jobs active at any given time, whereas with v6, 30k jobs and it didn't break a sweat.  I never did see what the top-end was.
I made the assumption that the bdb vs classic spooling was one of the differences that made things better.  We run what I think is a lot of jobs, 3 million+ per month, that are typically bursty.  (big flood of work, trickles down to nothing for a bit, and then another flood.)

The list is back!

I always use classic spooling for all my SGE6 installations. Is there a
real need for your site to use Berkeley DB spooling??
