It's not that - it's slow on just the main builds (x86 allmodconfig, arm multi_v7_defconfig and arm64 defconfig when I'm doing it). I think it's due to a combination of some degree of natural growth in build size and the builds now all being forked off at once rather than being run sequentially - the system ends up either context thrashing at the start of the build or using too few cores for the allmodconfig but I was too busy running the builds to experiment much.
My system isn't nearly so fancy as Stephen's which probably doesn't help here, I do keep thinking about upgrading so there's a good chance that next time I try I'll have done so. [unhandled content-type:application/pgp-signature] | |
