Description

"Inserting and deleting objects takes up to 20 times longer when the database server isn't on the same machine as the database client.
Especially object graphs, where the top level object provides a lot of child objects, are more than lame."

Config batchMessages as true to see whether it improves the performance by following code:

Db4o.Configure().ClientServer().BatchMessages(true);

The test case commits every change after every operation.

We suggest do batch commits, say, 1 commit after 100 operations.
