Factorio performance is 40% lower when using the Linux version of the game

I tested the problem on Ubuntu20.04 and Debian11 (Testing build with latest updates).
In the folders i attach performance comparison only for Debian11(testing) and win8.1x64.
Ubuntu has same reduced perfomance.
The hardware configuration in both logs is the same. Graphics settings are minimal.
Screen resolution, framerate and color depth was the same in both tests

I assumed that the problem might be related to the number of logical cores, tried to disable and enable hypertrading in Linux, but this did not affect performance in any way.
Also i assumed that problem can be related with Nvidia SLI support, but perfomance not changed with installed\removed SLI connector.

My hardware: intel i9-7900x, 56Gb DDR4 3000mhz, 2pcs Nvidia 1080ti in SLI mode, NVMe samsung 970


tested applications downloaded without steam via theese links directly:
https://factorio.com/get-download/1.1.41/alpha/win64
https://factorio.com/get-download/1.1.41/alpha/linux64

My save and logs available at link:
https://drive.google.com/file/d/13BEZ7d ... sp=sharing

Please tell me when my request was processed on email danshin063@gmail.com,
and give me advice which part in my system was a bottleneck.
I can rapidly provide additional info if you wish.
Thanks in advance for any help!
