counter-intuitively the list impl was faster than the heap the theory was the heap did more comparisons and swapping so even though it benefited from no interface and some cache locality, it was still slower the idea was to just use a raw slice kept in order this avoids the need for interface, but can take same comparison approach as the list it seems to work out: go test -run=xxx -bench=. -benchmem -cpuprofile=cpu.out BenchmarkTop10of100000Scores-4 5000 299959 ns/op 2600 B/op 36 allocs/op BenchmarkTop100of100000Scores-4 2000 601104 ns/op 20720 B/op 216 allocs/op BenchmarkTop10of1000000Scores-4 500 3450196 ns/op 2616 B/op 36 allocs/op BenchmarkTop100of1000000Scores-4 500 3874276 ns/op 20856 B/op 216 allocs/op PASS ok github.com/blevesearch/bleve/search/collectors 7.440s |
