I actually have a pretty bad machine wrt. writeout behavior here (hp nx5000), so i will test this. early writeout is right now about ~4-5 seconds faster (it takes ~6-8 seconds to do the final sync without early writeout). But this machine also is not really faster with compression enabled. With compression enabled, i get a flickering disk led during write, without it is solid on. Since it is a Pentium M 1400, CPU speed should be fast enough to benefit from compression. It also was always dog slow with in-kernel suspend. Short: this machine looks like it is the right candidate for this kind of benchmark, since i can probably see every small amount of improvement of writeout speed easily :-) -- Stefan Seyfried QA / R&D Team Mobile Devices | "Any ideas, John?"
