the choice of some of these benchmarks is weird. they have a bunch of cpu-bound benchmarks. why exactly would you expect these to change as the kernel changed? (i would expect changing compiler to have a bigger influence.)<p>the ones that do change (and improve mostly) are ones where the kernel actually plays a role--file system, network, etc.<p>the iozone benchmark is a bit surprising, it shows no improvement. but they are hitting 200MB/s, so i wonder if this is simply because linux is hitting the max speed of the disk.<p>all in all, not very useful.
