Dunno if anyone mentioned it...
I have improved home network streaming (3D and UHD files from a NAS) by replacing old CAT5 LAN cables with new CAT7 ones... 
At £2 - 5 a piece it's not a big expense but it prevents needless problems, from my experience...

Although I see little value in these tests in relation to VPN performance, except for theoretical crypto performance, I will add results of a N3150 CPU with AES-NI support.
They by no means reflect real world performance, for that one needs to test in a real world scenario.
1. Hardware crypto support (AES-NI) disabled:
2. Hardware crypto support (AES-NI) enabled:
3. Hardware crypto support (AES-NI) and hmac-sha1 (Hashing)
In case of OpenVPN, as a minimum one wants data to be encrypted, determined by the cipher directive.
Lowering cipher to AES-128-CBC will help somewhat.
One could also disable the hashing (auth none), determined by the auth directive, for data packets to take away load from CPU.
Even though our set-top-boxes generally do not support AES-NI, we will still somewhat benefit from AES-GCM when OpenVPN 2.4 becomes available end of December...
