Quick Start

HttpServer.create()
        .handle(req -> {
            req.onData(buf -> {
                // handle http content 
            });
            req.onEnd(p -> {
                req.response()
                        .setStatus(200)
                        .end("Hello ESA Http Server!".getBytes());
                return p.setSuccess(null);
            });
        })
        .listen(8080)
        .awaitUninterruptibly();

Performance

Test cases

• We built an echo server by ESA HttpServer and used a http client to do the requests for RPS testing with different bytes payload(16B, 128B, 512B, 1KB, 4KB, 10KB)
• Also we used origin netty to build a server which is same with above for RPS testing (uses the HttpServerCodec, HttpObjectAggregator handlers directly).

Hardware Used

We used the following software for the testing:

• wrk4.1.0

• 	OS	CPU	Mem(G)
  server	centos:6.9-1.2.5(docker)	4	8
  client	centos:7.6-1.3.0(docker)	16	3
