what's the performance of ulfius. I need concurrency , how to evaluated the amount of concurrency of ulfius.

Good jod. i havet use u code in some of my project, i want to use it in my iot server. it need concurrency,how to evaluated the amount of concurrency of ulfius??

[babelouest]

I haven't made any real performance measures or benchmarks, so I can't tell you the amount of concurrency a program using Ulfius can handle. If you want, you can try to make some.

Usually, ab is a good program to test an http service.

[skylli]

thank you, i will try later. Is ulfius creat an thread to handle each http request ?

[babelouest]

Yes, there is one separate thread per connection.

[tibbis]

@babelouest but ulfius_send_http_request() will not be on a separate thread right? Only web sockets?

[babelouest]

@GitTibbe , ulfius_send_http_request() is different from ulfius core webservice, it's the http client function and uses libcurl underneath. But it doesn't run any thread in the background.
Its behaviour is thread-safe according to libcurl documentation.

Ulfius websocket server is another part of the framework. When the websocket connexion is established between the client and the server, a single thread is executed to handle all incoming and outcoming websocket messages.
But the websocket thread is independent from the core webservice.
