Almost surely there are several causes that all can lead to contention.

We already found:

 *  client side causes (while the client helds to commit lock)

   - garbage collections (which can block a client in the order of
     10 to 20 s)

Interesting.  Perhaps someone might enjoy investigating turning off
garbage collection during commits.

A reconfiguration of the garbage collector helped us with this one
(the standard configuration is not well tuned to processes with
large amounts of objects).

what'd you do?
