I have a raspberry model B (the first one) and it acts as a DLNA server through my local network.
A few days ago I tried to watch a film streamed by the rasp, it was full hd and sometimes it used to lag.
I made this calculation: File size: 6GB -> 6000 MB Movie length: 2,20hh -> 140 min -> 8400 sec
6000/8400 = 0,7MB/s = 5,6 Mbps
This should be the maximum required bandwidth for the streaming, right? How could it be?
I know some raspberries have problems with LAN speed, but 6Mbps is ridiculous!
I thought the problem might be the processor, so I'm thinking of buying a newer Raspberry Pi 2. Could this help in your opinion?
What else could it be? I have the raspberry linked to the router via LAN, same with the PC so I'm not using wifi! Also, the video is stored in an external HDD (WD MyBook Essential 1TB) self-powered.
