rjl493456442	a1b8892384	trie: improve node rlp decoding performance (#25357) ... This avoids copying the input []byte while decoding trie nodes. In most cases, particularly when the input slice is provided by the underlying database, this optimization is safe to use. For cases where the origin of the input slice is unclear, the copying version is retained. The new code performs better even when the input must be copied, because it is now only copied once in decodeNode.	2 years ago

Felix Lange	40cdcf1183	trie, core/state: improve memory usage and performance (#3135) ... * trie: store nodes as pointers This avoids memory copies when unwrapping node interface values. name old time/op new time/op delta Get 388ns ± 8% 215ns ± 2% -44.56% (p=0.000 n=15+15) GetDB 363ns ± 3% 202ns ± 2% -44.21% (p=0.000 n=15+15) UpdateBE 1.57µs ± 2% 1.29µs ± 3% -17.80% (p=0.000 n=13+15) UpdateLE 1.92µs ± 2% 1.61µs ± 2% -16.25% (p=0.000 n=14+14) HashBE 2.16µs ± 6% 2.18µs ± 6% ~ (p=0.436 n=15+15) HashLE 7.43µs ± 3% 7.21µs ± 3% -2.96% (p=0.000 n=15+13) * trie: close temporary databases in GetDB benchmark * trie: don't keep []byte from DB load around Nodes decoded from a DB load kept hashes and values as sub-slices of the DB value. This can be a problem because loading from leveldb often returns []byte with a cap that's larger than necessary, increasing memory usage. * trie: unload old cached nodes * trie, core/state: use cache unloading for account trie * trie: use explicit private flags (fixes Go 1.5 reflection issue). * trie: fixup cachegen overflow at request of nick * core/state: rename journal size constant	8 years ago
