my serviio setup
1.6 GHz 4gb ddr2
Most of my viewing is through Panasonic bdt230 bluray player.
The player and laptop have wired connections and stream local video fine.
My ISP is slow which limits what I watch online. And I can't get anything to work over wireless.
I think if I had dedicated server and faster connect speed serviio would be a lot more useful.
Also its worth mentioning my network has three routers. Two are used as switches. Serviio handles this fine.
I did have to get a modern ffmpeg for it to work though.
Besides my bluray I can stream to my phone or tablet., but if the source is online it only plays about 5 seconds. Then it stops.
