@genfunk
can you see if it's just a matter of waiting, or your case is total freeze?
if your cases are different it would be bad to mix it all up.
@rygrass
is all this stuff in a single folder, or spread in subfolders?
2.3 is not supposed to be 10 times slower, but from your description it's hard to understand what's wrong.
consider i don't know other cases, so it may be rare.
