Past reclen=16, speed is ok for me (I could live with it  ).
 ).
So why is speed so low when transferring file from my PC to the SSD on the Rock ? 
Those iozone numbers look good, though a little low on the write. 320MB/s read (as is shown on the final test) is close to the maximum of USB3 with overhead. Performance is always going to be terrible on small file chunk sizes (that's the reclen column -- 
record 
length) on any system, even with an SSD. 
 
But this shows that it's not a problem with the Rock64 (or at least not with the USB3 controller and UASP drivers). I'm not sure what could be causing the problem. You may want to check network performance on your R64 (try using iperf3).

SSD is a 128GB from sansdisk.
I'm really puzzled. 
Did you try running iperf3?

		I tried another file transfer and the speed for a 2GB file was at 100MB+/s.
When trying iozone, the result I had for 4k reclen test was similar to the speed I had when trying to transfer file.
So my guess was that the system file was not the right one... Now, I'll be able to go to sleep earlier tonight.
Being a noob sure is tiring ^^;
	
	
	
	
	
 
 
	
	
		Don't update. Once I mark it as a release (when it is tested and stable) you will be able to do it.
	
	
	
	
	
 
 
	
	
		hello
please help me with this
I have installed omv on a microsd card, fired it up, configs, everything great until I restarted the board to see if the ip address remains the same.
well, guess what? not only the ip address but even the mac address changes every time I reset the board or unplug the power supply.
how can mac address change? isn't every device hardcoded to generate the same address every reboot?
so of course my router assigns different ip every time cause of the mac.
what can I do?

thank you!
