import timeit

print("keccak")

setup = "from eth_utils import to_checksum_address"
run = f"to_checksum_address(b'00000000000000000000')"

print("to_checksum_address")
print(timeit.timeit(run, setup))

setup = "from eth_hash.auto import keccak"
run = "keccak(b'')"

print("keccak")
print(timeit.timeit(run, setup))

note: the original spec was missing one transcoding -- but even with that, the non-eth_utils implementation is way faster
