I think it's a processor speed issue. Lost packets could be an lwIP
configuration issue (have a look at 'lwip_stats.mem' and
'lwip_stats.memp' to check the 'err' counters). But 'TCP window full'
just means the PC sends faster than the device can handle.
I managed to run iPerf with ~100 mbit/s on an STM32 (with STM HAL
drivers fixed/improved by myself), but I don't remember the CPU speed...
It could also be a driver issue, but I think the ChibiOS drivers are
better than the STM HAL ones..
