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).



With my own new and faster hardware in box running a matured and updated openSUSE Tw Slowroll (system overview at the bottom here), I have updated and extended my own transcoding tests using ffmpeg-7 and SVT-AV1 v. 2.1.

For SD DV 576i -> AV1 the speeds increase from fps=50 at preset 4 up to fps=890 at preset 12, compressed file sizes 6-8%
For HDV 1080i -> AV1 the speed increases from fps=24 at preset 4 up to fps=376 at preset 12, compressed file sizes 16-18%
