unRAID UI/dockers is very slow during downloading/unpacking

[tone]

Hi, I am relatively new to unRAID (~6 months) and started noticing degraded service (usability, lag) in my unRAID media server. Things worked fine for a few months but now Plex is hanging every day, it takes 30+ seconds to view my Main page (unRAID UI).

I have tried restarting multiple times and it temporarily fixes it but not for long. At this point I think it might be SSD (a bit old) where my appdata lives. 

 

I have attached my diagnostics from today. I appreciate any help/direction.

You have an unusually large number of share configuration files, the .cfg files on flash in config/shares. Possibly many of these aren't being used, or possibly you have unintentionally created a lot of top level folders and so have a lot more user shares than you intended.

 

How many user shares do you show on the User Shares page?

@trurlLooks like I have 9, doesn't seem too crazy?

Also, I believe it to be linked to cpu iowait. Here is a screenshot from the Glances docker:

After researching a bit more:

 

I am trying CPU Pinning, will update when I have results:

CPU pinning had no effect. Continued research looks like there are many people with this issue, here is essentially the same problem and he explains the problem very well -- why is there a problem running unRAID/docker but the same hardware on Windows is fine (download/unpack/UI responsive-ness).

 

I have ordered another SSD and bet it will fix my problem. Shame so many people are having this issue and no one has solved it yet.
