Subject Re: Why the transaction down the performance so much???
Date Wed, 30 Nov 2011 17:12:48 GMT
For producers, only use transactions is you are sending more than one
message, so for batching. Jms already guarantees a disk sync when a
send returns.

For clients do what you wish.

Do try and cache connections/sessions/prodcuers
and if you have a single consumer cache that.

Remeber, transactions mean disk syncs, so you will always be limited
by the speed of a fsync to your disk.
