Can you give 2.6.22.1-iop1 a try to see what affect it has on sequential write performance? Download: http://downloads.sourceforge.net/xscaleiop/patches-2.6.22.1-iop1-x86fix.tar.gz Unpack into your 2.6.22.1 source tree. Install the x86 series file "cp patches/series.x86 patches/series". Apply the series with quilt "quilt push -a". I recommend trying the default chunk size and default stripe_cache_size as my tests have shown improvement without needing to perform any tuning.
