I have zero experience with SSH. What I have noticed just from observations during different types of test is that core 1 seems to be more responsive to NAT type stuff while core 2 reacts to heavy wifi usage and based on the vpn test core 2 also appears to handle the vpn traffic/encryption. When not using the openvpn client I'll see high core 1 usage and negligible core 2 usage during speedtest.
Look for the RT-AC1900P model as it's the newer version of the 68U and has the same dual core 1.4 Ghz processor as the 88u/3100. Make sure to read this thread before purchasing a 1900 class Asus router. http://www.snbforums.com/threads/rt-ac68u-rt-ac68p-rt-ac1900-rt-ac1900p.35759/
I ended up getting two AC1900P model from Best Buy, I'll report back of my speeds when I have them setup.
Thanks!
