I have done this test on my desktop, with a client on my desktop, or with a client on another desktop (100 Mb/s ethernet). The volume of transfered data is not enormous, it's around 1kb per message, so for 2000 messages per second, it's around 16 Mb/s, far under the maximum network capacity. The

sockets are never closed, and no new threads are being created.


advice? Any clue?

Ok, I have reached my limit, I don't know MINA enough to go farther ... Any

How is the threading in MINA configured?

For low latency, I recommend:
 * Ensure TCP_NODELAY is set
 * No ExecutorFilter
 * Bump IoProcessor threads instead

I've had good results doing that (for high-connection, small- message oriented things).
