It is very, very easy to run vanilla Linux (or even OpenBSD) on their hardware. I do exactly this:

Octeons (not Octeon-TX) are amazing processors. Ubiquiti makes killer hardware. I hear their software is junk but wouldn't really know since I always erase it immediately after unboxing.
It's a big honking MIPS chip with firehose connections to the ethernet PHYs. Precisely the kind of device you want for a router.
What are the thruput measurements on OpenWRT when compared to ER-.. stock firmware, with hw accel or with DPI..?
I have an ER-4 to be able to use the entire wan connection, but on stock firmware I must disable DPI to enable hw acceleration (otherwise the thruput floors). I don't use DPI atm, so no big loss.
Can you utilize the hw accel in openWRT too?
Are we talking DPI at 1Gbps symmetric?
