Windows 11 vs. Ubuntu Linux Performance On The Intel Core Ultra 7 Meteor Lake
7-Zip was slightly faster on Linux than Windows 11 for this laptop.
For single-threaded audio encoding tests with FLAC, WebPack, and MP3 formats, Ubuntu came out slightly ahead of Windows 11. This single-threaded testing was one of the areas I was most curious about to see if there was any significant difference that may indicate poor E vs. P core selection on either operating system. But the results at least for these tests were close.
Windows 11 was slightly faster with libjpeg-turbo.
