Neha,

Thanks. We are on 0.7.2. I have written on another thread on the list here
about one of the reasons we are stuck - the absence of a PHP client for our
front end producer systems. (On a side note, would appreciate if any inputs
can be given on that thread as well)

When you mean performance, do you mean throughput ? We did measure
throughput with our default configuration of 1000 ms for the flush interval
value, and the much lower 100 ms value I proposed on this thread. Our
numbers were identical - for a single broker we were clocking at around
20,000 messages read per second on the consumer side. Using a small 'n'
brokers we can easily exceed our target numbers. (The load was
synthetically generated - using a likely message size and at a rate that
seems reasonable for our producing side).

Given this observation, do you suggest any further tests / measurements for
us to be sure ? Would appreciate any inputs.

Thanks
Hemanth
