Change paralell to threads. Save ~200 msec in my machine 1.7 sec to 1.5 sec

buybackoff commented 8 months ago

I tried that even in the first attempt: https://github.com/buybackoff/1brc/commit/f1b81f8a590a8a42d5be8358e6ba30489e678592#diff-c23b3a4b594cd434906b503ac730336620a2a9854b42a783b2978c254b358a30R111-R114

Simple tasks, long running tasks, threads, PLINQ - it makes no difference.

Do you have turbo boost enabled on your CPU? If so, the numbers could be very unreliable.

Turbo boost is enabled in my processor. Could you run my project to prove or disprove the hypothesis?

It doesn't work this way. It's my project and I said already that it does not matter, tried multiple times. PLINQ looks nicer.
