just to make sure; this exact same workload but with the stock scheduler does not have this effect? if so, then it could well be that the scheduler is too fair for it's own good (being really fair inevitably ends up not batching as much as one should, and batching is needed to get any kind of decent performance out of disks nowadays) -- if you want to mail me at work (you don't), use arjan (at) linux.intel.com Test the interaction between Linux and your BIOS via http://www.linuxfirmwarekit.org - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
