| Summary | 0020251: Use kernel mode PPPoE rather than User mode | ||||||||
| Description | User mode PPPoE uses considerably more resources and appears to restrict the speed of PPPoE connections more than kernel mode. As an example, on a Core-i5 machine, the ppp0 process consumed 35% CPU while limiting connection speeds to about 290Mbps on a 1000Mbps connection. Switching to Kernel Mode increased the speed to c. 790Mbps and CPU usage was not noticeable (did not appear in "top"). These days 1000Mbps connections are becoming more common and ClearOS is restricting their use. All that is needed to enable Kernel Mode support is to add a line: LINUX_PLUGIN=/usr/lib64/pppd/2.4.5/rp-pppoe.so to: /etc/sysconfig/network-scripts/ifcfg-pppX It could either be done for all pppX interfaces or by a preference. Going back in time, Kernel Mode PPPoE was developed during the 2.2/2.3 kernels and was released mainstream in 2.4 so it is well tried and tested. There is more information in the rp-pppoe sources.

From https://www.linuxquestions.org/questions/blog/kostya-519950/pppoe-roaring-penguin-vs-kernel-pppoe-issues-and-solutions-3565/ [^] and Ben's testing it needs a firewall rule: iptables -t mangle -I FORWARD -p tcp --tcp-flags SYN,RST SYN -j TCPMSS --clamp-mss-to-pmtu Also from the same article it looks like the plugin can be invoked from /etc/ppp/options with a line: plugin rp-pppoe.so |
