Most of the other Packets have constant sizes. Ive added this to the message chunking branch, we now only create the buffers to the size we need. The max buffer size in configurable via the jbm-config file via the 'remoting-max-buffer-size' attribute. Ive ran the the perf examples with max buffer size set to both 1k and 64k with tcp-nodelay enabled and disabled and the results were on par with trunk on my lap top. I wouldn't mind some real figures if anyone with a couple of machines and a switch minds running some with some different settings?
