I'm using Total Commander for a long time already (since 2014), and had no problems with it. But last several months I'm using constant problems with all dialog windows - they opens very slowly, at least several seconds (2-10). It causes a lot of pain.
Window examples: New Folder (F7), Copy (F5), Find Files, literally everything.
What did I check:
- Another PC - fail, issue reproduces on all my PCs (3 of them)
- Clean config - fail, issue reproduces without any plugins
- 32/64 bit version - fail, issue reproduces stably on all architectures
- Check using Sysinternals Process Monitor - well, nothing suspicious here. Few config/registry requests, then long idle pause. Looks like totalcmd.exe does some internal work during this.
- Update Total Commander to the latest 9.51 - no changes here.
- Downgrade to the 6.56 - much better (1 second instead of 5) but still not perfect. The same is in the 8.01 version (1-2 seconds), so problems are crazy only in the 9.0+.
My current suggestion is that everything started after certain windows update (Licensed Win 10 everywhere, updates regularly) - may be some winapi call became very slow.
Alternative one (quite strange, but probably) if some network request is done during such procedure (e.g. license validation). I check without the license key - no difference though.
What else should I check? Any ideas? Some profiling may be? I'm professional software developer, so I'm ready to try any advanced methods.
