I have an TP-Link Archer C7 and i'd like to install openWRT (which i never did before). So far i have learned that my version is not ideal for openWRT. Currently the main reason for switching from stock to OpenWRT is the fact that i want a DNS Server and like to provide a VPN Service through my router.
On this page i've read something that might stop the whole thing.

"Furthermore, please be aware that OpenWrt firmware does not support the hardware NAT capability of these routers. Hence, the throughput between WAN↔LAN will be slower than with stock firmware. This is only important for users with highspeed internet connections, like e.g. a 1G fibre connection. If your internet connection is ⇐200Mbps you don't need to worry about this (maybe even up to 300Mbps)"

Is that still the case? My "problem" is that i do have a symmetric 1Gbit fiber connection. If so i'll stay with the stock firmware.
I have two devices that are online pretty much 24/7. A Raspberry Pi Model B (Raspbian) that i use as a printer server and my HP Proliant Microserver (Debian Jessie). Is it ok to run dnsmasq and openVPN on the Raspberry Pi or should i go for the server? I'd expect the VPN performance to be rather poor on the Pi.

Pi's are pretty lousy for high-speed networking since the ethernet chip is only 100Mb and if you want to add another, it is all funneled through one USB2 connection to the CPU.  If your want to keep up Gb performance end to end, you'll need something with a lot more CPU than the C7, like a multi-core X86 box.

Which would mean I'd have to use my Server. It has two eth devices and also enough CPU Power.
Well. Since i am going to get a apu2c4 sometime in 2017 this is only am temporary solution.

Fast Path on LEDE, can bring Gigabit routing to C7
