I finally have some numbers for this patch. The benchmark was ran using Linux 5.1-rc4 and defconfig.
On Juno2: * hackbench 100 process 1000 (10 times) * .7% quicker On ThunderX 2: * hackbench 1000 process 1000 (20 times) * 3.4% quicker I am happy to try other benchmark if you think it is useful. Anyway, I will resend the series with the comments addressed. Cheers, -- Julien Grall
