Is your feature request related to a problem? Please describe.
I am currently using RemoteBlockchainStorage for testing my on-chain contracts, and while I use snapshot and loadFrom with specified block numbers, the process is still quite slow. Each transaction takes 1-2 seconds to test, which makes the overall testing workflow less efficient.

Describe the solution you'd like
I would appreciate any optimizations to reduce the time required for test execution, such as caching, lightweight transaction simulation, or parallel execution, to speed up the testing process.
