Interesting... It looks like _getLinePoints in widgets/point.py is one of the biggest problems. Is that correct? This is a function I have considered recoding in C++, but SIP seems to be fairly painful to use so I've never got that far. The main problem I've had with it is getting it integrated into the build system properly. Are you using a recent Qt version? They fixed a bug which made plotting lines very slow in X11 if they were long (even if clipped).
