const GasMultiplier = 100

GasMultiplier is how many cosmwasm gas points = 1 sdk gas point SDK reference costs can be found here: https://github.com/cosmos/cosmos-sdk/blob/02c6c9fafd58da88550ab4d7d494724a477c8a68/store/types/gas.go#L153-L164 A write at ~3000 gas and ~200us = 10 gas per us (microsecond) cpu/io Rough timing have 88k gas at 90us, which is equal to 1k sdk gas... (one read)
