Is there a way to speed up how long Cura takes to slice?

Is there a way to speed up how long Cura takes to slice? I have a top end PC and when calculating a 45hr 0.06mm layer height print the CPU load is only 8%. Id love to have an option somewhere that allows it to hog 90% of cpu resources to get the slice done quickly.

Not that I know of.

Also, for someone who has been playing around with this stuff for a few years, this is pretty hilarious to me. Three years ago even a simple cube could take a couple of minutes to slice. Something more complex and large could literally take hours.

Thanks for the reply Robert. I have your feeder mod on my ultimaker 2 extended, its awesome!

There really should be some ability to speed it up if the system resources are there though. I understand when its slow on an old PC but im running a 5960x 8 core cpu at 4.4GHz with 32Gb of ram and a 1200MB/s ssd.. imagine what it could be like if it used those resources.

It's not that simple. Using multiple cores means using multiple threads which has a pretty big impact on the complexity of the software. Most of the slicing must be done in sequence, so it wouldn't even give you that much of a speed boost.

It should use a full core though, so I can't explain the 8% CPU usage.
