So you are stressing directly the james-mailbox project, not the james-server?

If you persist in a database via JPA, set openjpa.streaming to true in james-database.properties, it will put less pressure on the memory and gc, especially for large attachments.

Thx, Eric

Hi Joshua,

One more bit of info - what are you using on the client-side to
retrieve the messages? Any details of that configuration (envelope,
fetch parameters etc) could be useful.
