Each account storage has indirection which requires extra read, register (8 bytes), and node (96 bytes)

Issue to be solved

Each account storage (e.g. "private", "public", "storage") has 8-byte register which is used to construct a new register path that leads to actual StorageMap.

This indirection requires an extra read, extra register (8 bytes), and mtrie node (96 bytes) for every account storage.

Suggested Solution

We can directly store the StorageMap for each account storage and remove the extra 8-byte register and 96-byte node for each account storage.

Although this solution does not require migration, it would be cleaner to do it in migration.
