I've tried https://github.com/hashicorp/golang-lru/tree/master/simplelru today and here are the results: with LRU cache: ``` Benchmark10Clients-2 50000 29021 ns/op 3976 B/op 105 allocs/op Benchmark100Clients-2 3000 363432 ns/op 36382 B/op 1005 allocs/op Benchmark1000Clients-2 500 2473752 ns/op 360500 B/op 10009 allocs/op Benchmark10ClientsUsingTheSameQuery-2 300000 4059 ns/op 773 B/op 15 allocs/op Benchmark100ClientsUsingTheSameQuery-2 500000 4360 ns/op 773 B/op 15 allocs/op Benchmark1000ClientsUsingTheSameQuery-2 300000 4204 ns/op 773 B/op 15 allocs/op ``` without LRU cache: ``` Benchmark10Clients-2 200000 5267 ns/op 616 B/op 25 allocs/op Benchmark100Clients-2 30000 42134 ns/op 2776 B/op 205 allocs/op Benchmark1000Clients-2 3000 552648 ns/op 24376 B/op 2005 allocs/op Benchmark10ClientsOneQuery-2 1000000 2127 ns/op 462 B/op 9 allocs/op Benchmark100ClientsOneQuery-2 500000 2353 ns/op 462 B/op 9 allocs/op Benchmark1000ClientsOneQuery-2 500000 2339 ns/op 462 B/op 9 allocs/op ``` > How were you using the lru cache exactly? I was adding a KV pair each time there is a match plus checking if `lru.Contains(key)` before running the actual check (`q.Matches(tags)`). ``` key = fmt.Sprintf("%s/%v", query + tags) ``` |
