Hey,
I updated my server from 6.8 to 6.10 and now pretty much everything runs with high CPU load and/or slower then before the update.
iperf is somewhat slow.
Before the update I was able to move files from a local machine to the server with the full 1Gbit/s and now im only getting 70-80MB/s.
In the GUI it looks like there isn't even any activity on the cache drives until the transfer is nearly done and then it goes up to the ~500Mbit/s of my MX500s for the last few seconds.
When moving files on the server the speed normally went up to ~400MB/s and now hovers around 140MB/s.
One measurable slowdown is with my duplicati backup. It normally took 1-2 minutes when nothing has changes and only the checks were running. It now takes 5-7 minutes.
A minecraft server I set up a few days ago ramps up my CPU to ~90% with one player connected.
Before the update four players were able to play without that much load on the CPU.
Plex also uses nearly 100% when transcoding for one user and ~50% when direct playing.
That are the things I noticed so far, I think.
I don't understand what is happening here. The network isn't up to snuff and the CPU is overloading constantly.
The drives seem to be fine, when checking the speed via the DiskSpeed docker.
(One of my array drives is collecting `Reallocated sector count` errors, but I'm already in contact with Seagate for advanced RMA. And as this seems to be a problem when using the cache drives, I don't see how that could be related)
UnRAID forgot the settings for the SMART notifications after the update so I was getting the "normal" `current pending sector count` errors every MX500 gets. I didn't find any other settings UnRAID "lost" after the update so far.
I attached the diag archive.
Can someone make any sense of all this?
Thanks in advance.
