hi Asankha, how many messages you sent for one scenario test? i.e for eg 500b message with 640 threads
In the very first scenario upto 640 concurrency level both have same through put while for 1280 threads UE has a sudden increment and for 2560 other ESB has a relatively high change. What could be the reason for that? Are all these results repeatable? thanks, Amila. On Thu, Feb 11, 2010 at 12:52 PM, Asankha C.
