Comment 3 for bug 987593

Slow down with the pen (bezier) tool observed using current trunk (r11350) on OS X 10.7.3 (64bit) with default (new) preferences in new document (from default template), if snap delay is reduced to '0' (zero), and the size of the current document window is increased (e.g. fullscreen (F11) or maximized (WM)).
System: Gtk+/X11 2.24.20, glib 2.32.2, cairo 1.12.2

The apparent relation to the snap setting is puzzling me:
- Performance is back to normal after hiding the status bar
- GTK+ theme, or other gtk settings do not matter
- Behavior seems to depend on the size of the canvas area displayed in the current document window (not necessarily tied to full screen or maximized state)

Not reproduced with same settings on Mac OS X 10.5.8 (32bit),
System: Gtk+/X11 2.24.8, glib 2.28.8, cairo 1.10.2.

Could you please compare on your system:
1) What setting do you have for 'Inkscape Preferences > Behavior > Snapping > Delay'?
   (Default is 150 ms)
2) Does it also occur when drawing in a smaller (not fullscreen nor maximized) document window?
