Would it be possible to get a new dropbear package? Preferrably, compiled to allow -c none?
The reason I'm asking is that currently, my remote rsync is slow as molasses and my DNS-323's spend 95% of their time on dropbear. It's been going for well over two weeks, and is about 20% done.
Given that the units are right next to each other on a private LAN, I have no need to encrypt the data transfer - if I can get my units to spend most of those 95% on more valuable things, there's a chance this might actually finish before summer is over :-)
