here some more tests with fastd directly, i dont see any big difference between salsa20 and salsa2012, but i big difference in direction ... which is somehow new for me. i will not do the different wireguard testings with different ciphers, as i am still struggling in building valid reproducable kmod..ipk packages for LEDE so i think fastd testing is finished by this (which at all only was to compare to our existing setup) - a small notice : OpenWRT Wiki was wrong with CPU speed of TPlink841v11 - it is not 560MHz, it is 650Mhz - if somebody ever want to compare another embedded device greetz Jens 2016-08-16 06:36:42 +0000 --- Verbose: new session with <foo> established using method `salsa20+umac'.
