Ark and "extract" really slow

I had gotten used to the fact that Ark in Neon was really slow, but after installing Kubuntu 23.10 last week (I use it as a portable OS), I was reminded how slow. It is about 10x slower. This has always been the case since I started using Neon. It works fine, just feels like 20 years ago. Anybody else find ark or the context “extract here” function to be underperforming? Any ideas how to speed it up?
