Our early tests with DB 4.6.1 thru 4.6.3 showed impressive performance

Were those speedups confined to, say, write, or general?
In general. You might recall that Jong-Hyuk Choi had done some work
identifying
bottlenecks in BDB's memory management; Sleepycat never used the code that
Jong
sent them but they still rewrote their memory manager between DB 4.5.20
and
4.6.1 as a result of Jong's work. Since the memory manager affects all
operations in the DB library, the speedups can be seen everywhere.

If support for 4.2 is dropped in the next 2.4 beta, what is the earliest
version we think we will support?
