Quite probably, if that was the default. Can you
point me to any other things I should be changing
(eg. stripe size, in particular). Given the myriad
different possibilities and very limited time, I
didn't experiment to choose optimal block size or
stripe size.
I don't have the bonnie benchmarks to hand, although
they were quite acceptable - bottom line was 13 MBytes/sec
throughput IIRC. I posted them on linux-raid before,
so you should be able to dig them up from the archives.
