Hi All, We are working on kernel version 2.4.20 and are trying to migrate to version 2.4.31. We are doing some performance related tests to see the impact of migration. The routing throughput seems to degrade from 2.4.20 to 2.4.31. We have a Malta board with mips 4kc processor and are using iperf tool to do the testing. Two test PCs are connected to the malta and iperf server is run on PC and the client on another PC. With netfilter compiled into the kernel, version 2.4.20 shows better result than 2.4.31. No rules except the default (all accept) have been applied. Without netfilter, both perform almost identical. Is this expected ?? The dump below shows the measurements. If anyone has done similar tests before, please share with me their results.
Have a nice day.
