1d4afb5ceSopenharmony_ci# lws minimal http server with multithreaded service 2d4afb5ceSopenharmony_ci 3d4afb5ceSopenharmony_ciLws supports multithreaded service... build lws with `-DLWS_MAP_SMP=<max number of threads>`, the 4d4afb5ceSopenharmony_cidefault is 1. If nonzero, some extra pthreads locking is built into lws and it supports multiple 5d4afb5ceSopenharmony_ciindependent service threads. 6d4afb5ceSopenharmony_ci 7d4afb5ceSopenharmony_ci 8d4afb5ceSopenharmony_ci 9d4afb5ceSopenharmony_ciWhen an incoming connection is accepted, it is bound to the pt with the lowest current wsi 10d4afb5ceSopenharmony_cicount, to keep the load on the threads balanced. Only the pt the wsi is bound to can service 11d4afb5ceSopenharmony_cithe thread, so although there can be as many wsi being serviced simultaneously as there are 12d4afb5ceSopenharmony_ciservice threads, a wsi can only be service by the pt it is bound to. 13d4afb5ceSopenharmony_ci 14d4afb5ceSopenharmony_ciThe effectiveness of the scalability depends on the load.
