I mentioned that "100%: emX taskq" occurs only on that interfaces where GRE packets are being processed. External interface to Internet feels great. Pings are <0ms and load is 9.57% with 14kpps (input/output). Maybe interesting: According to kgmon: % cumulative self self total time seconds seconds calls ms/call ms/call name 39.9 93.10 93.10 1643247 0.06 0.07 rip_input [10] Is it em related or mpd related or something else? Back to releng_6? Not sure though. :( -- Oleksandr Samoylyk OVS-RIPE
