http-cache's Issues

Performance improvements

Hello.

1. I'd suggest to consider using of fasthttp to reduce HTTP-library overheads.

A related issue: julienschmidt/httprouter#117

To make this project really useful you need to be faster than this:

2. Also, mutexes are slow. Especially on massively-concurrent cases (which a caching server is about). You may consider to use atomicmap instead (method GetByBytes to get a value) — it is oriented on a lot of reads (less writes and unsets [it's required to use LockUnset(), ATM :( ]).

http-cache/cache.go

Line 36 in 91198cf

c.Mutex.Lock()

Or, may be, it would be better to implement own mutexless thread-safe map.

3. You're coping data (and doing a memory allocation) here:

http-cache/cache.go

Line 24 in 91198cf

if value, ok := c.Map[key]; ok {

I'd suggest to use pointers, instead.
