Additional testing has shown that the heap collector performs significantly better when larger numbers of hits are requested. The heap is also faster (though very close) when fewer (10) hits are requested. Here are the numbers from my laptop: slice: go test -run=xxx -bench=. -benchmem BenchmarkTop10of10000Scores-4 5000 396943 ns/op 2472 B/op 26 allocs/op BenchmarkTop100of10000Scores-4 2000 630894 ns/op 18848 B/op 116 allocs/op BenchmarkTop1000of10000Scores-4 100 14996445 ns/op 176552 B/op 1016 allocs/op BenchmarkTop10000of100000Scores-4 1 1878796320 ns/op 1857768 B/op 19023 allocs/op BenchmarkTop10of100000Scores-4 500 3858309 ns/op 2480 B/op 26 allocs/op BenchmarkTop100of100000Scores-4 300 4270086 ns/op 19000 B/op 116 allocs/op BenchmarkTop1000of100000Scores-4 50 30163705 ns/op 178024 B/op 1016 allocs/op BenchmarkTop10000of1000000Scores-4 1 3429557237 ns/op 1882008 B/op 19023 allocs/op PASS ok github.com/blevesearch/bleve/search/collector 16.316s heap: go test -run=xxx -bench=. -benchmem BenchmarkTop10of10000Scores-4 5000 341064 ns/op 2552 B/op 27 allocs/op BenchmarkTop100of10000Scores-4 3000 501922 ns/op 19744 B/op 117 allocs/op BenchmarkTop1000of10000Scores-4 1000 1759088 ns/op 184744 B/op 1017 allocs/op BenchmarkTop10000of100000Scores-4 50 25954696 ns/op 1939608 B/op 19024 allocs/op BenchmarkTop10of100000Scores-4 500 3814933 ns/op 2560 B/op 27 allocs/op BenchmarkTop100of100000Scores-4 300 4009369 ns/op 19896 B/op 117 allocs/op BenchmarkTop1000of100000Scores-4 200 6397276 ns/op 186184 B/op 1017 allocs/op BenchmarkTop10000of1000000Scores-4 20 81815315 ns/op 1963912 B/op 19024 allocs/op PASS ok github.com/blevesearch/bleve/search/collector 14.980s |
