Summary	0000416: Sketcher: Slow Solving Peformance when adding unconstrainted arcs to Sketch
Description	Just raise an issue in the solver with performance in solver: If you add many (e.g. 10) arcs. The solver takes very longer the sketch - even without any constraints. I find it may take 0.005s to solve on my machine. This delay clearly shows when dragging any other point such as line. I have noticed this doesn't happen when adding many lines or circle geometries to the sketch. It should be reproducible all the time. Its perhaps worth an investigation.

logari81 2012-04-13 19:40 developer ~0001943	Did you compile FreeCAD with -O2 or with -O0?

abdullah 2016-01-08 16:14 manager ~0006691	Maybe in connection with the Sketcher improvements of last year. This problem is fixed.
