RE: RE: [openjms-user] For OpenJMs Developers : OpenJMS Performance with Persistent Messages and Durable subscribers..

Performance is largely determined by:
. the connector you are using
. the database

The rmi and tcp connectors are the fastest.
Try switching between the two to see if one works
better for your setup.

Same goes for the database - try several implementations to
work out which gives the most performance for your platform.
