I meant it continuously regresses from .23 including 26-27 timeframe. There were at least two changes in 26-27 which caused tbench regression in this particular time interval. One of them enabled TSO over loopback by default, so one can turn it off via ethtools or this patch: http://marc.info/?l=linux-netdev&m=122263663631600&w=2 another (hopefully) one I'm trying to find out, which is a bit complex and slow, since e1000 driver changes in the middle of the 26-27 timeframe does not allow my testing machines to boot. So, there is a regression (partially resolved), but it is only part of the problem. -- Evgeniy Polyakov -- To unsubscribe from this list: send the line "unsubscribe kernel-testers" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
