Gave the v6 patchset a try on a system with 1920 logocal cpus (sixteen 60 core Sapphire Rapids sockets with Hyperthreadding enabled).
Without the patchset it took 71 seconds to start all the cpus.
With the v6 patchset it took 14 seconds to start all the cpus,
a reduction of 57 seconds. That is impressive.
Full boot, to root login prompt, without patches takes 223 seconds.
This patchset reduces the full boot time by 57 seconds, a 25% reduction.
Well done.
Output with the patchset:
