The company line is that BDB is faster than a relational server
because you have to go out of process to fetch a record from a
standalone server, but with Berkeley DB, the IPC turns into a
function call. Of course, I'm speculating about the performance
of a relational server implementaiton that doesn't exist, so we
don't need this nail hammered all the way into the wood :-).

Thanks. I appreciate it.

If you have questions or problems during the implementation, you should
let us know. Email to support@sleepycat.com will get our attention.
Be sure to mention that you're working on Subversion. I do encourage
you to make 3.2.9 the basis for the release, since newest code has the
most known bugs fixed. 3.1.14 and 3.1.17 are in wide deployment now,
and work fine, but if you get to choose, go for 3.2.

I'll make a note to ping you again in a couple of months. Thanks a
lot for the quick response on the Web site.
