Ok, I've traced the problem down to 2 places.

If no filters are entered we always apply this filter: - meaning we always have to check it which we never did before
None => (Operater::GreaterThan, 0),

The Moving of this line down a bit in dir_walker.rs (it is needed because having it is faster than a file lookup).
if !walk_data.allowed_filesystems.is_empty()

Yes, you are right. I'm sorry that this PR of mine caused the performance to drop so much. I will revisit the performance of my code!

No problem, We live and learn. I should have checked more.
