Finally got a chance to do a wired speedtest. This was done using a USB 2.0 > Ethernet adapter into my Razer Blade. I don't know if that introduces any ping degradation vs. a dedicated gigabit ethernet port, but I doubt it.
In other news, I got my first bill. They forgot to apply my 3yr contract discount, so the internet portion was charged at $799. A quick phone call fixed that, so total for this connection, one static IP, and a business telephone line with long distance capability is going to cost me $238/mo after all taxes and fees.
While it looks like YouTube is going to be just fine at 720P/1080P with a little buffering, other higher bit-rate streaming services are going to top out at 480P, but gaming looks very promising at 12ms! We are further from LA, which is a relatively popular server location, but at least this old tech doesn't look like it's going to take gaming off the table. Patches/re-downloads are going to take forever, though!
Picked up a DropCam for keeping an eye on construction while we're out of town, let's hope having it constantly uploading doesn't tank these numbers too much. I read it should take up about 0.5 Mb/s of upload, not sure if it will affect ping, though.
