Well i report about performance regression before too, seems related case, but my report was unclear. And the bug was terrible for me, it was causing very bad performance on REDIRECT and loopback transfers. I am testing also recent net-2.6 with this loopback changes, it seems improve things for me much. So it is really important bugfix for me too. There is always chances that some fix will cause regression, i will try to test this changes on intensive real-life workloads to make sure all fine. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
