Hi,
I see a performance dip on 3.2.0:
7% busy - 3.0.2
8% busy - 3.2.0
Under 10K load
Built with -O2 optimisation and configured as './configure --enable-tproxy=force'.
records.config attached for each version -
Platform = Linux RHEL6.2/Intel Xeon
Latest traces I have:
(not much sticks out other than (ink_freelist_free and ink_freelist_new, the %gap between them is always bigger on 3.2.0 but maybe not related to the diff ?)
Would anyone have tested this with the above configuration?
Thanks,
/aidan
