Slightly off topic, but if I'm aiming to get the fastest 'make -jN' for some random C project (such as the kernel) should I set N = #P [threads] + #E, or just the #P, or something else? Basically, is there a case where using the E cores slows a compile down? Or is power management a factor?
I timed it on the single Intel machine I have access to with E-cores and setting N = #P + #E was in fact the fastest, but I wonder if that's a general rule.
