Hi , I performed the routing and bridging tests on Linux kernels 2.4.31 and 2.6.16 on a MIPS(4kc) malta Board , with and without iptables rules. I observed that the routing performance is quite better( 15-20% increase) on 2.6 for shorter packet sizes( 64,128 and 256 bytes) and almost equal to that on 2.4 for larger packet sizes(512, 1024 and 1518 bytes).
The bridging performance follows the same pattern as well. Is there something I might have missed..? Is this an observed behavior on 2.6 kernels..? I have included the throughput figures for bridging for both 2.4 and 2.6 kernels in the table below. Packet Size(bytes) 2.4.31(Mbps) 2.6.16(Mbps) ------------------------------------------------------------------------------------------ 64 2.11 2.19 128 3.59 3.75 256 6.33 6.48 512 10.93 11.16 1024 17.49 17.33 1280 20.00 19.83 1518 22.09 19.91 About the tests, the MIPS malta board has two D-Link PCI ethernet cards. A bridge br0 is configured over the two ethernet interfaces ( eth0 and eth1). There is an external traffic generator that is configured to generate packets of above mentioned sizes and to measure the throughput correspondingly. Please let me know if you need any more information.
