it seems v1.11.x has less throughput than v1.7.x and v1.9.x?

The best approach will probably be to (re)design your application to avoid string copies where possible, e.g. use ngx.re.find instead of ngx.re.match, string...

it seems v1.11.x has less throughput than v1.7.x and v1.9.x?

Hello

We have openresty v1.7.2.1 in production for a long while and are going to upgrade it so we do the stress test, of course, on the same application codebase. But it's disappointed when getting the result:

v1.11.x(I had tested 1.11.2.1, 1.11.2.2 and 1.11.2.3rc1) seems to afford less (about 15% decreased) throughput than v1.7.x, but 1.11.x have the less response time(TP99 decreases from 25ms to 20ms). it dont make sense at all. IMHO, it can process more requests if it's faster.

I have test v1.9.x (1.9.7.2 and 1.9.15.1). It seems have neither increase nor decrease than v.1.7.x.

I have the lua-level flamegraph and they have the same trends. so I capture the flamegraph and they seems have some big differences but I have no idea.

v1.7.2.1-C-level: https://drive.google.com/open?id=0B6BhdPcYDd4cWEpDakY4ZW5reUU

v1.11.2.1-C-level: https://drive.google.com/open?id=0B6BhdPcYDd4cR2hiQVZ6U3NsdDQ

Please do not cross-post. It's annoying. FWIW, the discussion happens
on the openresty (Chinese) mailing list below:
