Date: Mon, 11 Aug 2008 13:36:38 -0500 From: Christoph Lameter <cl@...ux-foundation.org> To: netdev@...r.kernel.org CC: lkml <linux-kernel@...r.kernel.org> Subject: tbench regression on each kernel release from 2.6.22 -> 2.6.28 It seems that the network stack becomes slower over time? Here is a list of tbench results with various kernel versions: 2.6.22 3207.77 mb/sec 2.6.24 3185.66 2.6.25 2848.83 2.6.26 2706.09 2.6.27(rc2) 2571.03 And linux-next is: 2.6.28(l-next) 2568.74 It shows that there is still have work to be done on linux-next. Too close to upstream in performance. Note the KT event between 2.6.24 and 2.6.25. Why is that? -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
