Hi Christophe!
I don´t think MS Access is an issue here.
Usually Access is a lot faster than real Client/Server DB Engines
principally because it has nothing to do with them, it is almost a raw file
on your disk.
What may be an obstacle is the JDBC-ODBC bridge, that is slower than a
native JDBC driver.
As far as I know the real problem must be the Entity Bean pool. If the pool
is not filled up at start time then a "new" must be performed every time you
issue a create() method against the home object. This is true until the
number of instances of the Entity Bean class reaches the maximum pool size.
Question: when you test the server with 10,000 creates() do you request
Entity Beans with the same or different primary keys?
Thanks.
