Yes, all such things I have disabled / removed.

I don't think so. I tried even running Windows in diagnostic startup (safe
mode / running with only core processes and services) and it had no effect.

I was looking at it some time ago and it didn't seem like processor is too
much busy, but as I think about it, it is suspiciously almost not busy at
all ... ~1 % of processor usage. On laptop it fluctuates between 5 and 10 %.
I'm talking about usage when benchmarking the "store" code.

No, only open thing is Playground from which I run the benchmarking codes.

"654.738 per second" on desktop
"1,271 per second" on laptop


Thank you all for ideas.
