db4o

This release comes with an improved client/server protocol, which is now completely asynchronous and able to batch messages. Both changes reduce the number of client/server message round trips, and therefore improve client/server performance.

This release comes with a new BTree architecture and major performance enhancements resulting from a new query processor that runs on the new BTrees. Deterministic immediate query responses were made possible using a new "Lazy Query Evaluation" algorithm.

This release is a performance release. It uses a
new BTree architecture for class indexes to reduce
the time for commits dramatically. New marshallers
for strings and arrays improve insert and update
performance by achieving a better clustering of
slots. A new diagnostics package provides more
help for developers to develop fast applications.
All performance improvements also lead to a lower
memory consumption, emphasizing db4o's suitability
for embedded use on low ressource systems.
