FastHTTP

FastHTTP is the fastest and reliable HTTP implementation for Go. FastHTTP is tuned for high performance, with zero memory allocations in hot paths. In benchmarks, both FastHTTP server and client have shown to be up to 10 times faster than those of net/http. However, FastHTTP does not provide an API identical to net/http, but it is better to write FastHTTP request handlers by hand so as to make use of all its advantages. One of its key advantages is that unlike net/http it does not limit many optimization opportunities, such as reusing existing objects per request and avoiding unnecessary memory allocations.
