"...So it's totally overkill, but my servers and router all talk to each other over 10Gbit/s links. It's mainly because of my impatience when moving lots of data around, and it serves that need well. It's unlikely I'll ever saturate a 10gbit link with my current setup, but it's also unlikely I'll need to upgrade anytime soon, unless I start collecting a lot of discs again. Thanks to a dedicated GPU for transcoding and an 8 disk wide raidz2 pool, I can handle 10 simultaneous streams with over half of them converting to something other than original quality, all while using less than 100Mbit/s of my upload bandwidth. Speaking of, my damn ISP doesn't support IPv6 natively, so I had to use a Hurricane Electric tunnel. Works well enough, but browsing the internet with it sucks 'cause a lot of CDNs just kinda consider a lot of their IP blocks as suspicious. Sometimes I get extra captchas, sometimes sites don't load at all. Outgoing is just fine though! Probably a third of streams are over IPv6 - isn't that cool?"
