Comparing files in Synchronize Dirs is terribly slow

[Sob]

It seems that TC redraws the whole list over and over again while comparing files. There is visible flickering, which I wanted to report first. But then I noticed it's the smallest part of the problem. It's so bad that two directories already read before (= cached in memory) take ~35 seconds to compare using TC 8.0 beta 1 (both 32 and 64-bit) and it uses 100% of one CPU core for the whole time. Comparing the same directories using TC 7.56a takes about one second.

Unfortunately I don't see this problem here (it's very fast and not flickering). Do you use AeroGlass, or the basic theme (like AeroGlass, but no transparencies), or the old Windows theme?

I use classic (win9x) theme.

This is how it looks: http://web.hisoftware.cz/sob/img/tc80b1x64-compare-flickering.avi (4MB)

It's from 64-bit version. In 32-bit TC it's slightly less visible, but just by a tiny little bit, no major differences. The slowness and big CPU usage remains.

Tested: Win7 x64, Win2008R2, WinXP32, all also with clean ini. It's the same everywhere.

OK, I will test it with classic theme.

Fixed in beta2.
