James, I've run a whole truckload of benchmarks on raid1 with varying
chunksizes on three different kernels, and on a plain disk. I'm about to
publish some of the stuff, but I'm wondering very hard why is it that the
readbalancing test showed _awful_ numbers on tiotest 0.21 and great
numbers on 0.24 - any idea? Just have a look:
[this is big - my apologies]
