I would stay away from Ubnt routing. Which features that requires disabling packet processing off-loads and the performance impact is not well documented and varies between models and software versions.
There appears to be many bugs related to off-loading as well. The below example is what finally made me decide not to consider Ubnt routers. It may be fixed now, maybe, but even if it was broken for way too long and shrouded in too much mystery, not even making it obvious which models are effected (the thread title was not always that specific either). I can't take Ubnt seriously, even for a home environment, after seeing how basic forwarding is that poor and it's not even their highest priority.
The only good thing that this proves is that at least they don't censor their forums, trying to hide issues.
