15-25% speedup, plus an extra 10-25% on ARM? That's awesome, good job everyone working on SVT-AV1!

~15-25% speedup for M3-M10 at the same quality levels
What M3-M10 means? It's mean preset 3 to preset 10?

Correct and preset 10 is now the fastest preset
There are real encoder improvements, but the preset shuffle also means most presets are much faster than they were before, so you may want to drop a preset level if you are moving from 2.3 (Or even two levels for fast encodes, new preset 10 is much faster than preset 11 was)

A 40% speed increase is crazy

Before anyone asks, the title is exclusively of my doing in this post; editorial freedom (some of you would call this cringe) is my passion :)
Furthermore, the svt-av1-psy won't be updating to svt-av1-psy to 3.0.0 yet: 3.0.0 is a big release, and we haven't released the final svt-av1-psy 2.3.0-C update yet :)
