v1.31 and v1.30 are both much slower than v1.21

Especially when it comes to raw MD5 you can be sure that we have a close eye on it's performance. Note that the default workload settings have been changed. If you want to do a good comparison, remove --force and make sure to use the correct driver and use -b -m 0 instead of doing a run. The code used in multihash is the same.

There's was no speed loss between 1.21 and 1.30 as you can see here: https://hashcat.net/misc/p130_img/changes_v130.png
