Slow transfer speed into Unraid


Recommended Posts

Hi,

I've just build an Unraid server using Ryzen 3700X and X570 motherboard. I'm getting really slow transfer speed over gigabit network and no cache.

 

If I use Windows 10 laptop to copy from my QNAP NAS, I'm getting an average of 30-40MB/s. If I use rsync, this starts at 50-65MB/s and eventually slow down to 1-3 MB/s. If I use MC, it slows down to under 10MB/s. QNAP is showing CPU and RAM utilization of less than 10%. Unraid CPU (Ryzen 3700X) is showing one of the core hitting 100%. Its a random core but always hitting 100%.

 

Additional info: Parity is on, using Unraid version 6.8.0-RC5.

 

Anybody else having the same issue?

If parity in syncing, then slow in speed will be expect.

It include IOwait, so don't worry, it isn't CPU not powerful enough.

Just want to post an update to this.

 

Not sure what happens, but 1 core of the CPU is pegged at 100% even after stopping all dockers, VMs and checked that no processes was running. I ended up rebooting the machine and when I tried copying again, now the speed of copying is consistently between 60-70 Mb/s, I guess I'm still not getting gigabit networking speed but much better than before.
