I'm using an Raspberry Pi2 Model B as a NFS file server in my LAN.
If I copy a 3.3 GB image file with "rsync -av" from an encrypted drive on my laptop to an encrypted USB drive on my Pi2 I get a transfer speed of ~ 12MB/s.
Does anyone know how much speed I would gain in the same scenario with a Pi3 (just about..)?
You haven't said what kind of speeds you would expect on your LAN for similar kinds of transfers between other computers, and the network itself is a significant factor.
- Laptop (i7 / 16GB Ram)
- wifi (300 mbit / 3 meter distance from Laptop to router / just 2 devices in that wifi )
- Forgot to mention: I have a 1Gbit Lan Adapter on the Pi2
From another computer with better I/O and stronger CPU I would expect a lot more.. at least as much as the wifi can handle.
Only if the Pi currently does this with a very high processor usage, say 75%+. This would indicate it is working hard to deal with the encryption, and might benefit from more horse power there.
Pi2 CPU load is > 75% when copying..
