-m 15700 = Ethereum Wallet, SCRYPT is known (like any scrypt-based algo with high cost factors) to be GPU-unfriendly and that it performs better on modern and fast CPUs (like Intel i9 or new Ryzen).
It's always difficult to "brute-force" a slow hash type. That's nothing unexpected.
It also should be your very last resort... often it's much better to try other attack types, like rule-based dictionary attack.
It's clear that if you try each and every combination of 6 random bytes that the number of combinations ("keyspace") is huge and that it will take a lot of time. most of the times brute-forcing is not the most efficient, nor most clever strategy.
I don't see anything unexpected here, except the fact that you are not aware of trying to use a modern CPU (instead of GPU) for SCRTYPT hashing algorithms.
