rant-go
Rant is the simple X clone built using an experimental high-performance HTTP server. It allows you to watch you my short messages, search for them either on the client or on the server and subscribe to updates using RSS.
Server is built using Go and assembly without any packages, except for package runtime and its dependencies from Go's standard library (only because modern Go doesn't allow you to build executables without loading it with runtime.a). Currently only freebsd/amd64 is supported.
HTTP server supports only GET requests. Query parameters could be included but must be parsed by hand. It also supports pipelining, infinite keep-alives and a lot of concurrent connections.
For an incomplete C version of this server, see rant-c.
Performance
Using wrk I've measured performance of net/http and my server using rules of Plaintext benchmark. Results on my i7 6700K with 32 GiB RAM, sending 16 pipelined requests and receiving text/plain Hello, world\n responses are following:
net/http:
$ ./wrk -t 4 -c 256 -d 15 --script plaintext.lua http://localhost:7070/plaintext -- 16
Running 15s test @ http://localhost:7070/plaintext
4 threads and 256 connections

Both server and wrk were running on one computer. For each server wrk parameters were selected to produce the best results.
