I did the test with nginx+luajit and got ~ 40k/second on the json test. I think that's about all you are going to get out of a large instance. Of course, nginx was only using a few MB of RAM... .

resty.mysql
ngx.ctx
looks like the code https://gist.github.com/bakins/5322735#file-luajit-benchmark-as-a-module-L29 connects to mysql on every request. what's normal way to connect once in init_by_lua and use the connection?or, is there connection pool library?

http://wiki.nginx.org/HttpLuaModule#tcpsock:connect "Before actually resolving the host name and connecting to the remote backend, this method will always look up the connection pool for matched idle connections created by previous calls of this method (or the ngx.socket.connect function)." And from resty-mysql: The resty.mysql object instance cannot be stored in a Lua variable at the Lua module level, because it will then be shared by all the concurrent requests handled by the same nginx worker process (seehttp://wiki.nginx.org/HttpLuaModule#Data_Sharing_within_an_Nginx_Worker ) and result in bad race conditions when concurrent requests are trying to use the same resty.mysql instance. You should always initiate resty.mysql objects in function local variables or in the ngx.ctx table. These places all have their own data copies for each request.

For such a simple benchmark, coding it like you would a more complex "real" project may have some performance impact. Of course, all the tests I did showed an improvement with my changes.

Round 4 is out. Openresty seems to do worse than in round 3. http://www.techempower.com/blog/2013/05/02/frameworks-round-4/ 2013/4/24 agentzh <age...@gmail.com> Hello!
