Message-ID: <20040224034036.22953169.akpm@osdl.org> (raw)
I took the various patches in -mm for a quick ride. Dual CPU, mem=64m,
`time make -j4 vmlinux':
2.4.25 2:57.34 2:45.62
up to blk_congestion_wait-return-remaining 5:41.52 5:56.37
up to vmscan-remove-priority
up to kswapd-throttling-fixes 7:44.53
up to vm-dont-rotate-active-list 6:29.23
up to vm-dont-rotate-active-list-padding
up to vm-lru-info 9:28.47 6:14.70 5:11.99
up to vm-shrink-zone
up to vm-shrink-zone-div-by-0-fix 9:13.21 8:17.29
up to vm-tune-throttle 7:39.89
up to shrink_slab-for-all-zones 7:06.27
up to zone-balancing-fix 7:46.15
up to zone-balancing-batching
up to zone-balancing-batching-fix 4:44.76 4:27.02 4:05.56 4:31.66 4:06.76
Based on this, and on your totally contradictory benchmarking, all I'm
prepared to say is that kswapd-throttling-fixes slows things down, and we
don't know why. The rest appears to be worth zilch. Possibly they slow
some things down as much as they speed other things up.
