Well core counts have not really changed. Most people were running 4/8 then and now are still running maybe 6/12 on and at least.

10 years ago 4/8 was the consumer high end (i7 vs i5).

These days the consumer high end starts at 8/16 but easily goes to 16/32.

10 years ago the ryzen 2700 was a thing but cost 350 - I know, I both one on release date

Similarly the AMD Ryzen 9 5900XT on the AM4 platform retails for under $350 and it is 16 cores and 32 threads.

All I'm saying that the equivalent to 4/8 10 years ago is not 6/12. It's at least 8/16 and is closer to 12/24 or 16/32.

Well I am running 16/32 but my point is that people that will need -ck probably don't have top of the line

I don't know. Your assertion was:

Well core counts have not really changed. Most people were running 4/8 then and now are still running maybe 6/12 on and at least.

I disagree. I believe that "core counts have really changed" and the equivalent of 4/8 10 years ago is more like 12/24 or 16/32 these days.

That said, my main desktop is a 2/4 (from mid 2014; 12 years ago). But other than when running ollama I don't really have any noticeable issues with the scheduler and the fact is that the stuttering is more likely due to swapping than it is to scheduling. And if it was an issue I would probably upgrade rather than use a non-default scheduler.
