I feel like you are running into a 100mbit cap somewhere besides the RPi. I Got a few 3b+ units just last week, fired one up with a 1tb usb disk on samba and large file upload/download sustains at 19MB/s. Its still not going to compete with even a cheap dedicated NAS device but its a good step in the right direction thanks to the ethernet bump. If the Pi could get even Multiport USB 2.0 on the SoC (like the Asus Tinker has), that would free things up quite a bit without the struggle to get to USB 3.0.pretoriano wrote: ↑Mon Mar 26, 2018 9:17 pm
Then, I expected RPI 3B+ to increase my network performance since we now indeed have a gigabit chip. But I guess my bottleneck is in the USB 2.0 bus and not in the network chip. I still have the same ~10MB/s performance (I do see peaks of 11 to 12 MBps but not sustained).
I do not think there is anything I can do to improve this since I believe the bottleneck is in the USB bus and so this may very well be the maximum speed these boards will have until (hopefully) we see anything bigger than USB 2.0.
If anyone has any thoughts or recommendations please share.
