October 23, 20232 yr Hi there, I'm trying to troubleshoot the speed to which I can copy to and copy from my hard drives. I'm was getting only about 10MB/s on a new install. I have 5 WD reds (CMR) at 5400rpm (2 parity). I have a 2.5 gbe nic and switch. I'm copying from a device that doesn't have 2.5 gbe however I can do link aggregation. Copying files to my laptop, I'm hitting near 30MB/s over wifi. This old NAS also has the same drives as what is in unraid. I found an article that suggested turning on turbo writes and that has helped, I'm pushing 17MB/s now but I think there is performance being left on the table. It doesnt matter if I write to my M.2 either, I get the same speed. I feel as if there is a network configuration issues but Im not sure where that could be. Any other suggestions that might help with my transfers? I was moving to this new server and I don't want it to take a week to copy my data over lol Id also Like to add that my parity checks run at 140MB/s so I dont think there is an issue with unraid and the disks. I can switch to the built in 1Gbe nic and get the same speeds as my 2.5gbit nic. Really seems like an unraid setting or configuration issues I am missing...

So iperf keeps telling me that the address is in use no matter what I change the settings to. I was able to run it in client mode on the server and server mode on my laptop. Im getting 30MB transfers using iperf.

I'm getting the same speed no matter if I use my cache, 1 gbe nic or 2.5 one. I've swapped my cables out 2 or three times. Everything is connected to the same switch. Other devices on the same switch can talk at much higher speeds. I've tried raising the mtu and that hurt performance down to 12 MB I'm really unsure what else I can try
