The difference between ldbm and bdb became significant when indexing came
into the picture.
So this may be a sign that we should improve the bdb indexing system
My data loads always find indexing to be the biggest bottleneck with BDB.
Our systems that index multiple things went up two hours in indexing time
between 2.1 & 2.2 with BDB (from 7 hours to 9 hours). I was able to drop
this to 2 hours (7 hours less!) by use the new shared memory key. On our
master (which indexes only 3 or 4 things), the load time takes
approximately 25 minutes, on both 2.1 and 2.2.
I have it down to do a bunch of dataloading, so I can provide more concrete
results in the next week or so.
