[[6.7.x] Very slow array concurrent performance]

All good.  I wasn't accusing you of ignoring, just wanted to make sure the core issue  is understood.

Yeah, I read that and understand the philosophy, but I wonder if just a simple "Thanks, we've seen the issue, we'll come back when we have something or need more info" would help qwell the fears.  Or even a thread label like "Investigating" or ""Accepted", then they can stay away from posting.

 

Anyway, that's all for another thread.

That's a fair point:  a secondary tag of "accepted" and then "closed" (when appropriate) would alleviate a lot of anxiety.

Do we think that intermittent latency problems with a VM could be traced back to this as well?  The VM is not on the array (nor cache) but booted from a dedicated nvme drive passed through.

 

It is incredibly frustrating to try and chase down intermittent problems...

[[6.7.x] Very slow array concurrent performance]

Anecdotal evidence here ( I have been watching this thread carefully ), but when I was doing some large copies (TBs moves using unBALANCE) I found that all of a sudden my winVM was experiencing significant latency issues.  This had not been an issue previously.  I just found it odd that it surfaced... and the thread had recency on my mind.  Maybe just Baader-Meinhof.

 

Probably unrelated (the VM exists on a dedicated nvme that sits in UD unmounted when not in use), but thought it worth noting.

 

I am going to try and something more objective (large copies while streaming UHD from Plex - which has never stuttered)

 

Cheers.

 

EDIT:  Hmmmm - slight performance degradation, but still not stalling and constant buffering that others noted.  (on side note:  Thor Ragnarock, great fun).

 

EDIT2:  Intersting. I am again moving a large data set.  I went to start a VM and the page just hung.  VM manager is no longer accessible via the GUI as well.  Again, don't know if related, but odd.  Will see if I can access once move completes.
