Optimise the HAMT_BIT_WIDTH parameter for majority use cases #17

Closed alexytsu closed 2 years ago

alexytsu commented 2 years ago

Currently, we have supposed a bitwidth of 5 is ideal for the HAMTs.

This constant should be determined empirically by simulating actors under use with large balances and transfer volume.

It should probably also be overridable by consumers if they wish to customise.
