I think the RB750Gr3, HAP AC2 and RB3011 should be sufficient for the traffic mix of most home users. I have a friend on TIME 500Mbps who torrents a lot (20TB+ ZFS backed seedbox in the closet) and he's using the older RB750Gr2 without any noticable issues. With fasttrack enabled it does the 500Mbps up/down single connection speedtest individually with the CPU usage peaking around 50-60%~. Of course, if he tries to fully saturate his upload and download simultaneously it becomes a bottleneck.

I'm just going with the CCR route so I don't run into any bottlenecks once I start terminating my site to site VPNs on the unit, enabling IPSEC (being forced to turn off fasttrack occasionally), OSPF routing, etc.

...

At least these are all the things I tell myself because I've been eyeing a CCR for the home since the 1036 came out and never really had a solid reason to get one

All 5GHz is using only ac?

I have found that some devices, especially Apple will cling onto n, rather than moving to ac when n range and good signal.

The Apple network stack is a PIA compared to other devices.
