Performances

Hi again :)

What performance can we expect with the following configuration :


2 servers :
- Linux
- Tomcat 5.5.9
- Embedded OpenJMS server, 0.7.7-alpha-3
- A router/firewall


Clients have subscribed to their server with HTTP.
Servers have (durably-)subscribed to each other with HTTP.
Publication are called via RPC (we use the embedded connection to publish)
Only one topic.
We send ObjectMessage with a dozen of criteria.

As I can see, 
Publish a message : 10ms
Receiving a message : 120ms

During one test, I sent 47500 non persistent messages, it took 8mn to publish 
everything and 8mn to receive 1600 messages before OutOfMemoryException. I 
guess OpenJMS server must be overloaded.

These performance are far from our expectations.

There are 3 publishing process. We must be able to send simultaneously :
1000 messages every 8s (non persistent)
10000 messages every 8mn (non persistent)
50 messages every minute (persistent)
 

Can we hope a better performance by tuning OpenJMS or not? Do we need to watch 
other JMS implementations or is it impossible? Do we need to do something 
different from JMS ?

Thank you for your help !

Eric
