According to Phoronix the Alliance of Open Media project quietly
released (the Intel based) SVT-AV1 v2.1 last week.
With this new SVT-AV1 release are yet more performance optimizations
and tuning.
The M0, M3, M5, and M6 presets are seeing 12~40% speed-ups while
maintaining similar quality levels to prior releases.
The compression efficiency of presets M11 to M13 meanwhile have
improved by 1~2%.
New SVT-AV1 benchmarks soon.

----------
Meanwhile, I have updated my previous tests using ffmpeg-7 and
libSvtAv1Enc2 version 2.0 on openSUSE Slowroll below.
The results are about the same speed +/- compared as my earlier
tests using ffmpeg-6 and SVT-AV1 encoder version 1.7

(Else I have purchased the hardware components to upgrade and
rebuild my workstations for a planned AV1 QSV/hw video transcoding:
mobo, Intel cpu and gpu, memory, ssd, cooler. More about this later.
But first I have to finish my ongoing DVD Video project).
