Ethernet performance was improved quite a bit by the introduction
of the etherusb kernel driver - before that, packets were going between
usb and ether queues via a user space process.
Any further improvement will probably be bounded by the simple synchronous

Compatible with user level software, yes. But it will need a new kernel,
because it has 4 x cortex-a7 cores compared with 1 x arm11 on the older pi.
The difference between Armv6 and Armv7 isn't it?

More asynchrony => fill more frames with packets.
hardkernel's odroid-c1 is similar and slightly better performance for the
same price; any sense which port might be easier?

Odroid-c1 is Cortex-A5 while Pi2 is Cortex-A7 so Pi2 is more
performant (but has worse ethernet and horrible
Does anybody know where to look for documentation on the changes, or
general documentation for the bcm2836?

Re: Ether speed
I was just asking in case there was a perfmormance improvment to be had for
free.
To be honest, the ether performance is not really a limiting feature of the
pi for me, if fact the cpu and ether are a fair match for each other.
A significantly faster cpu would upset this balance
Some documentation can be found here:
