`persist` is a hotspot when processing blocks because it is run at least once per transaction and loops over the entire account cache every time. Here, we introduce an extra `dirty` map that keeps track of all accounts that need checking during `persist` which fixes the immediate inefficiency, though probably this could benefit from a more thorough review - we also get rid of the unused clearCache flag - we start with a fresh cache on every fresh vmState. * avoid unnecessary code hash comparisons * avoid unnecessary copies when iterating * use EMPTY_CODE_HASH throughout for code hash comparison |
