Cura 4.8.0 running extremely slowly with multiple models

[TheDeejster 0]

I've been using cura for a bit now, and I haven't really had any big issues with it. However, today I split one "model" (it was an stl of multiple models) into its separate parts in cura. Having the pieces all as separate models (only 17 small models) absolutely tanked performance. The rest of my computer is still running perfectly fine, and has solid specs, which tells me that the issue is with the software and not my hardware. Anyone have a fix for this?

I split a "letters" thing using mesh tools

28 items on the plate

locked up a gigabyte gaming laptop I just bought because it ran slow adding support blocks on my old embedded graphics machine. about 8~12 sec per execution with that load.

 

dunno if that is normal or not

 

but Its very reproducible, so I'm sure the devs are aware
