Aliaksandr Valialkin 6b90570ed3 lib/uint64set: store pointers to bucket16 instead of bucket16 objects in bucket32 ... This speeds up bucket32.addBucketAtPos() when bucket32.buckets contains big number of items, since the copying of bucket16 pointers is much faster than the copying of bucket16 objects. This is a cpu profile for copying bucket16 objects: 10ms 13.43s (flat, cum) 32.01% of Total 10ms 120ms 650: b.b16his = append(b.b16his[:pos+1], b.b16his[pos:]...) . . 651: b.b16his[pos] = hi . 13.31s 652: b.buckets = append(b.buckets[:pos+1], b.buckets[pos:]...) . . 653: b16 := &b.buckets[pos] . . 654: *b16 = bucket16{} . . 655: return b16 . . 656:} This is a cpu profile for copying pointers to bucket16: 10ms 1.14s (flat, cum) 2.19% of Total . 100ms 647: b.b16his = append(b.b16his[:pos+1], b.b16his[pos:]...) . . 648: b.b16his[pos] = hi 10ms 700ms 649: b.buckets = append(b.buckets[:pos+1], b.buckets[pos:]...) . 330ms 650: b16 := &bucket16{} . . 651: b.buckets[pos] = b16 . . 652: return b16 . . 653:}		2021-05-25 14:27:52 +03:00
