hashcat 3 is faster than hashcat 4, if there are a lot of hashes.
what could be the problem?

I'm not clear from your post which tests are the ones that are for a large number of hashes.

And to clarify, by "Optimized" do you mean that you are using the -O flag?

judging by the tests the newer version the worse the performance. Sad
It is necessary to use old oclhashcat with which there are no problems.
yes used the -O flag

1080ti fe, if hashcat 3 slows down using hd6950 + oclhashcat 1.x, 2.x
