I noticed a 19% CPU utilization in Windows 10 with a 4th generation 3.6 GHz Quad Core i7 playing a DSD64 file
Utilization playing two 24/96 FLAC streams using LMS on my first gen 2.8 gHz i7 server is under 1%!

Apples and Oranges. Roon does LOTS more than LMS. And another inmate reported significantly lower utilization than Mercman. If the product does more I would expect it to use more (system resources). I think that's a perfectly reasonable expectation.

any digital player that truly required a fifth the processing power of a Cray 2 supercomputer for simple playback is too much!
You'll note that the original 19% figure apparently included some background processing load and is much lower in operation.
I doubt the software is written to be used on several thousand cores, so your reference to Cray is an ignorant one. Your 1/5 number also seems to have also been pulled out of your a$$.
(Supercomputers rely on parallelism to achieve their processing power and software needs to be written to utilize it. Google MPI or OpemMP is you're so inclined. Desktop applications have no need for any of this.).

Clearly you have no idea what a Cray 2 was. Like the Intel i7, it had four cores.
Cray 2 Supercomputer
Your 1/5 number also seems to have also been pulled out of your a$$.
At the expense of further confusing the issue with facts, an i7-860 delivers comparable whetstone and dhrystone benchmark performance to the Cray 2.
The background analysis can be turned off. Also, once all of the tracks are analyzed, it doesn't run. So real CPU was between 1 and 3 %.
