# 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
