Description
By improving the snapshot clean cache hit rate, we can improve the capacity of BSC further.
Rationale
According to the test, the cache hitting rate on BSC is about 94%, while the miss 6% IO will cost 32% of execution time.
We try to preload the state from DB by applying the transactions in advance. It turns out the execution time was reduced by 30%-40%
Example
Verified on testnet and mainnet.
