+ One thing we can safely say is that the default Berkeley cache
+ size of 256KB is way too low to be useful. Be careful setting
+ this too high though, as performance will degrade if you tell
+ Berkeley to consume more than the available resources. For our
+ tests, on a 256MB machine, we've found that a 128MB cache appears
+ optimal. YMM(and probably will!)V.

As you read this, it will be helpful to know that the
bsddb3Storage databases all use BTree access method.
