Guozhang Wang commented on KAFKA-2045:
--------------------------------------
[~rzidane] Although we have some thing like consumer / producer perf classes
for testing end2end performance we do not have the ones for testing per-module
performances (yet). What people usually do is just to use hprof / etc and check
the time split-up on functions.

> We need to add the memory management on the new consumer like we did in the
> new producer. This would probably include:
> 1. byte buffer re-usage for fetch response partition data.
> 2. byte buffer re-usage for on-the-fly de-compression.
