- Try to turn of CC
  -> if that help, try to only turn off real-time parsing of CC
- Try to turn off the SpellChecker plugin
- Try if other scintilla based editor like SciTE does slow-down, too
  -> if so, its a window manager issue

I tried --safe-mode (which should disable CC and spell checker) .. still the same effect ..
scite scrolls just fine .. as i mentioned scite scrolls about 10x more per full-wheel-scroll than does c::b

This is an old, old issue that hasn't been resolved. I spent a bunch of time trying to figure this out but I wasn't able to isolate the cause to a single factor. I can't remember if anyone tried running a minimal wxScintilla sample to see if the same performance issue shows up there. That may be worth exploring.

Kalith:
What about wxWidgets samples (if I understand correctly, wxScintilla has been integrated into wxWidget as wxStyledTextCtrl) ?
