Andy Green 954fcf2bc3 windows: clean LWS_WITH_MINIMAL_EXAMPLES warnings Fix pthreads detection in the minimal examples and add it where needed. Fix unistd.h include to be conditional on not WIN32 With this, -DLWS_WITH_MINIMAL_EXAMPLES=1 is happy and warning-free on windows.		2020-04-07 10:09:51 +01:00

lws minimal http server with multithreaded service

Lws supports multithreaded service... build lws with -DLWS_MAP_SMP=<max number of threads>, the default is 1. If nonzero, some extra pthreads locking is built into lws and it supports multiple independent service threads.

When an incoming connection is accepted, it is bound to the pt with the lowest current wsi count, to keep the load on the threads balanced. Only the pt the wsi is bound to can service the thread, so although there can be as many wsi being serviced simultaneously as there are service threads, a wsi can only be service by the pt it is bound to.

The effectiveness of the scalability depends on the load. Here is an example of roughly what can be expected

build

 $ cmake . && make

usage
