on rt2880 i also use rt-n15. the performance on rt2880 seeks unstable. sometime low. sometime high. i also don't know why. others target are more stable. so the maximum is 12x i got. by datasheet it support tx/rx checksum offload. but ralink sdk disable it. so i also disable it. so the performanc is not so good. i use netperf for test.
on mt7620 i only have fast ethernet ports work version. so the maximum is 94. i also have gigabit port device. but the switch can't work. so i can't test. so i focus on rt3662 device which with gigabit support. the most improve is tcp. the udp improve not so much. you can use ethtool to enable/disable some offload features. this improve on driver support SG so GSO is eanble too. also let GRO work by add rxvlan offload(by software). 2014-10-30 8:58 GMT+08:00 Roman Yeryomin <[email protected]>: > On 29 October 2014 21:48, John Crispin <[email protected]> wrote: > > Hi, > > > > i just pushed a huge update to the ralink ethernet driver. i want to > > thank Mingyu for taking so much time to fix all these details in the > > driver.
