I'm just started to experiment with cubieboard (1) as well. I've also noticed poor network performance at first, however later (without any tuning) it gave out 111 kBps. kern.eventtimer.periodic doesn't seem to affect it. I've also played with clocks a bit, and was able to increase CPU rate 3x by configuring PLL1. I've experienced some instability later (board doesn't always boot from USB, perl build fails), and now I'm checking if reclocking was the cause. -- Dmitry Marakasov . 55B5 0596 FF1E 8D84 5F56 9510 D35A 80DD F9D2 F77D amdmi3_at_amdmi3.ru ..: jabber: amdmi3_at_jabber.ru http://www.amdmi3.ruReceived on Sun Sep 21 2014 - 00:37:20 UTC
