Martin Holst Swende 5bf8769fb0 ethdb/memorydb, trie: reduced allocations (#28473) ... * trie: use pooling of iterator states in iterator The node iterator burns through a lot of memory while iterating a trie, and a lot of that can be avoided by using a fairly small pool (max 40 items). name old time/op new time/op delta Iterator-8 6.22ms ± 3% 5.40ms ± 6% -13.18% (p=0.008 n=5+5) name old alloc/op new alloc/op delta Iterator-8 2.36MB ± 0% 1.67MB ± 0% -29.23% (p=0.008 n=5+5) name old allocs/op new allocs/op delta Iterator-8 37.0k ± 0% 29.8k ± 0% ~ (p=0.079 n=4+5) * ethdb/memorydb: avoid one copying of key By making the transformation from []byte to string at an earlier point, we save an allocation which otherwise happens later on. name old time/op new time/op delta BatchAllocs-8 412µs ± 6% 382µs ± 2% -7.18% (p=0.016 n=5+4) name old alloc/op new alloc/op delta BatchAllocs-8 480kB ± 0% 490kB ± 0% +1.93% (p=0.008 n=5+5) name old allocs/op new allocs/op delta BatchAllocs-8 3.03k ± 0% 2.03k ± 0% -32.98% (p=0.008 n=5+5)		10 months ago
