Today I finally saw the ticket and took a look into it. Some update. In my computer (i7 3.10GHz with 8GB of RAM), I hit no memory limit (I am using the full sketches not the reduced version). Sketcher operations are under 1 minute, being the most time consuming assigning SketchB on a face of SketchA (around 30 seconds). I have a separate ticket just for J matrix formation (for reducing the sketcher memory footprint) and another one for the annoying group deletion messages. So I will close this. As ickby indicates, the "bottleneck" is the boolean operation (pocketing operation), in my computer it takes 7 minutes at full cpu (one core only as it is not multi-threaded) to show the pocketing dialog (5 mm) and another 7 minutes after hitting ok because it recalculates it (even if not changed). After that it goes fast rotating and moving the view at 0,1% deviation. As triplus says, if multithread support from OCC could be used (if available), then this should be around a 1 minute with 8 cores. Until then I, from the sketcher perspective, can do nothing significant to improve it. Note I am using a Debug version of FC compiling today's git. I do not know if anything changed in the meantime in other parts. |
