Folders on top adds a very noticeable lag every time you access a folder (500 ms or so on a top of the line mbpro). I experience this in column view. Is there any way to optimize this?
Can you download and test this version?

I confirm I have introduced some performance degradation in 1.7.11 to fix sorting issues.
First! Oh man…
Thanks for the quick reply. I’m afraid the improvement is marginal with this build. There’s still a pretty noticeable delay. Same goes for column width, by the way.

And http://downloads.binaryage.com/TotalFinder-1.7.10.dmg is slow as well for you? That was the last version prior my attempts to fix the sorting and introduced some display delays.
Thanks for the testing. I will probably introduce a switch. For people who want 1.7.10 speed and can live with potential folders-on-top sorting issues. I cannot deliver both at this point 
adding the flashing frame/frame for good measure: http://cl.ly/090e0W0o0L0l
I’m not sure I see the flashing frame. I see the right most column appear then resize. Is that what you’re referring to?
frame 1
previous folder with content
frame 2
new folder selected, column without content (white flash)
frame 3
new folder selected, with content and large column size
frame 4
new folder selected, with content and resized column
Ideally, the transition should go from frame 1 to frame 4 directly. At high speed, frame 3 makes it look like the folder contents are “flashing” because it transitions to white before updating.
