Network Speed: raspberries Vs bananas
Many of us want to use the Raspberry Pi to build a NAS, DLNA server, Samba shared folder or any project that makes heavy use of the network. Sometimes we forget about the limited Raspberry Pi capacity of bandwidth that has the Ethernet port and we forget alternatives like the Banana Pi.
Frank Mankel is a user of a Google Plus community on BPi and shows us how quickly he test it using iperf. Let's see the results of a file transfer over the network...
The file used has 3.1GB from a shared folder with NFS to a IntelNUC with the following results:
1. BananaPI 1 to my IntelNUC DC3217IYE
2. BananaPI 2 to my IntelNUC DC3217IYE
iperf -s

The transfer was completed in 1:03, which are approximately 50 MB/s. Remember that the speed with the Pi is about 6-8 MB/s. What do you think?
