Hey everyone, I am trying to hunt down with what appears to be a network problem. In fact, I upgrade the NIC in the server to an supermicro 10G with the x530 chipset thinking that it might simply be network saturation.
When I read from the server I can saturate the NIC on the slow PC to ~980 mbps. When I do write tests on the drive on the unraid box, it can write at about 330 MB/s (~2.5 gbps). When I try to write to the cache pool, it writes at about 60 MB/s (~ 480 mbps). It varies wildly when trying to write to the cache between 40 MB/s and 80 MB/s.
I noticed that if I turn off the VM service, unraid will write at 1 gbps. The VMs are not running on that drive pool and, in fact, they're quite VMs. One is a reverse proxy box and the other is a pihole with Splunk on it. They don't write or transfer much of any data.
Any thoughts on how to troubleshoot this issue?
