This benchmark compares cache algorithms using scrambled zipfian distribution (a few occur very often while many others occur rarely). Other distributions are supported too, but they produce similar results. You may also want to check cachetest.
The following libraries are supported:
- https://pkg.go.dev/github.com/dgryski/go-tinylfu
- https://pkg.go.dev/github.com/dgryski/go-clockpro
- https://pkg.go.dev/github.com/dgraph-io/ristretto
- https://pkg.go.dev/github.com/hashicorp/golang-lru (LRU, ARC, TwoQueue)
- https://pkg.go.dev/github.com/golang/groupcache/lru
- https://pkg.go.dev/github.com/dgryski/go-s4lru
And the results are:
<details> <summary>TLDR</summary>- TinyLFU works best for small number of keys (~ 100k). TinyLFU memory overhead can be tweaked with the 2nd argument.
- Clock-pro has significantly smaller memory usage with large number of keys (~ 1m).
- Segmented LRU has even smaller memory usage, but has inconsistent hit rate.
- Ristretto can still be a good choice if you need additional features it provides.
