I have been testing Linux as a bridge on a dual P4 (Xeon) system. I need to do packet mangling, mainly just send packets from specific interfaces to IMQ devices. The system has two Intel GigE interfaces (optical) and I use VLANs to create sub interfaces.
The test setup includes a packet generator (hardware based) that is sending 80 byte packets tagged with VLAN 500 between two ports (full duplex). When using kernel 2.4.20 I get about 160Mbps (highly depended on the specific packet size). I have two related questions: 1) After applying: ebtables-v2.0.003_vs_2.4.20.diff.txt and bridge-nf-0.0.10-against-2.4.20.diff.txt the performance under the same exact conditions drops to under 100Mbps (without any actual filtering configured). Why? 2) Is it possible to configure the bridge such that will either use or not use the bridge filtering code? Since not all the bridges will need to be filtered I would like to at least retain the performance on those bridges that do not need to be filtered. Thanks, Ron. __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.
