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.
