In lua resty https://github.com/pintsized/lua-resty-http, I saw we can use request_pipeline for requests. I am wandering whether this will increase the performance. While after reading the source code, I found the request_pipeline method is also implemented with the regular send_request, and a loop is used to send each request one at a time.
Seems it cannot help to improve performance, if it is the case, why bothering to have this method?
Thanks
