B2 says gigabit enabled, but throughput resembles 100mbit

Hello everyone,

I just installed a gigabit router in my home. The gigabit connection between my pc and the router is just fine, and B2 reports that the interface is set to Speed: 1000Mb/s (ethtool), however, when i copy files from my bubba to my computer via NFS (which has an SSD-drive) the throughput tops at exactly 10.00% the capacity of my gigabit NIC, which sounds an awfull lot like a 100Mbit/s to me

So, my question, even though both devices report gigabit connectivity, is there any reason why throughput should be limited to 100Mbit/s? I thought about drive limitations, but it does seem a bit odd that the drive would top out at exactly 100Mbit/s.

Any tips?

Thanks

Hi,

Run top at the same time and you will find out why.
FTP is faster than NFS, but NFS is much faster than SMB...

The B2 CPU just isn't quick enough to deal with it.
B3 is doing much better in this regard, but even that or even my power-hungry x86 machines can't reach the magical 1GBps. I think the fact you get exactly 100 is just a coincidence...

Best regards,

Thanks, seems like you are correct.
