REALLY Poor Perfomance

[kjp1231]

Not sure what is going on but I am getting really poor performance to my one FreeNAS box.

I was moving VMs to a data store on it and notice that it is taking TOO long to move. My ESX hosts are mounting my FreeNAS server via NFS.

Currently it is taking over 25 hours to move a 33GB VM from datastore on ESX to datastore on FreeNAS

FreeNAS has port channel of 3 1GB interfaces and ESX host has port channel of 2 1GB interfaces and they are both connected to the same Cisco 3650 switch. I am not seeing any errors on switch ports.

I tried copying a 2GB file from my laptop wirelessly to my QNAP NAS and it would take 5 mins to copy.

Trying to copy same file to either FreeNAS server takes over 45 minutes.

Looking for any guidance here, thank you

Have you tried without Port Channel?

Yeah, I tried on my second server I just stood up with a single 10GB NIC as well as a single 1GB NIC. Same performance.

How are you transferring your data? Are you using replication? Is it really 33GB or 33TB?
If replication is the mean, how many snapshot are present for this particular dataset?
If you have thousand of snapshot it will take a while to transfer, not throughput issues, mostly snapshot replication. This will appear as low to no CPU load, very low ethernet traffic.
Are you using compression better than LZ4, if so it will criple your system, but CPU usage would go sky high.
Are you limiting the throughput on your transfer?

Can you provide more details on your procedure and setup?

start with testing the performance of your drives local on the system then move to use iperf on the network. See if that gives you anything to go off of?
