Cache comparison benchmark for Go

This benchmark compares throughput and hit ratios of different cache packages. The benchmark is original used in Theine.

Feel free to create PR if you want to include your cache package, or open issue/discussion if you have question/requirement.

throughput

Throughput benchmark uses Go parallel benchmark, you can run it with:

make bench-throughput

Or

go test -bench=. -run=^$ -benchmem

hit ratios

hit ratio benchmarks use several widely adopted trace files:

The Meta trace file is too larger(> 1gb even gzipped), please download it from the link and put it in trace directory.

you can run it with:

make bench-ratios

You will see progress indicator(each dot represents 100k requests) when benchmark is running, result plots will be generated automatically in results directory after bench done.

Bench results will be cached in results directory with name: {client name}-{bench name}.data, this can make benchmark much faster when you are testing your package and run benchmark frequently. Just delete the file if you want to invalid cache.

add your cache package

First thing you need to do is wrapping your package to match Client interface:

type Style struct {
	Color color.Color
	Shape draw.GlyphDrawer
}

type Client[K comparable, V any] interface {
	Init(cap int)
	Get(key K) (V, bool)
	Set(key K, value V)
	Name() string
	Style() *Style
	Close()
}

Style is used to plot hit ratio results. if you only want throughput results, you can leave it empty. You can find more examples in clients directory.

Then you can add your client to either throughput or hit ratio benchmarks. Just update the benchClients var and add yours. You can include your plot results in PR, but I will generate them again and update README after merged.
