Slicing with these profiles is very slow! #17

Slicing with these profiles takes a long time! PrusaSlicer 2.0.0 does the basic slicing quickly but then the "Generating G-Code" can take minutes.

When I slice the same STL with built in Prusa profiles it takes just few seconds!

As an example: https://www.thingiverse.com/thing:3576952

To slice this with the unmodified settings of: Printer: Creality Ender-3 Stock Filament: Generic PLA Print settings: 0,20mm NORMAL Ender3

The initial slicing takes 7 seconds, Generating G-Code takes 3min 53 seconds

Now if I change the settings to: Printer: Original Prusa i3 MK3S Filament: Prusament PLA Print settings: 0.2mm QUALITY MK3

The whole slicing and G-Code generation is done in 10 seconds!

A huge difference! What might be the reason why the slicing takes so much longer time with these profiles?

Hello, disable avoid crossing perimeters. It's what causing the delay. The bigger the model the more it will take with that option

Yes, that helped thank you! I need to do some experimenting how much that feature actually helps, so if it's worth the extra time on bigger models

That's only usefull for Bowden to avoid cross perimeters and then retracts, that's it. If your retracts make no mess or trouble you can put that off

Yes, I have now disabled it from all the print settings. I will enable it again if prints get messy with certain materials and then see if it helps.
