Go uses freecache for caching

1. Introduction to freecache (hereinafter referred to as free)

A caching library for Go, with zero GC overhead and high concurrency performance, is it awesome?

2, free get

git official website: https://github.com/coocood/freecache
golang get: go get -u github.com/coocood/freecache
I personally think it is a better document: (I have to say that the big guy is well written)

4. Simple test

5. Supplementary Instructions

1. The code looks very simple, but you need to look at the source code and see how the documentation is implemented.
2. If you want to test the performance problem, teachers can test it yourself, here is just a simple implementation
3、 In the previous document, I wrote the cache of memcached. I think this is simpler, but the application scenarios are different. Memcached is mainly a distributed loop, and multiple projects can be accessed at the same time. Free is more suitable for a single project with high concurrent access.a lot.
