844 beta - CPU usage

[Spider99]

Reading the notes for the recent beta's i was expecting the cpu usage of the UI for DP to be less

 

With no balancing etc running its sitting between 5% and 15% - i.e. it doing something but there is no access to the pool drives

 

this is with an i7 so its using most of a single core - although the cpu is only running at 1 GHz (speed step) rather than 3.2GHz

 

this is on 2012r2

 

Wondering what its actually doing as there is no indication in the UI that its doing anything?

 

on win10 - creators update 844 is only using 0.1 to 1.0% again on a i7

This is most likely a rendering related issue.  

 

By chance, is the performance section open? 

 

But if you could run the StableBit Troubleshooter, and selected the "submit user interface memory dump" option, that should let us see what is going on, and help fix the issue.

And just FYI, the UI handles ... well, just that. the user interface.  Everything else (balancing, duplication, adding/removing disks, remote control technically) are handled by the service. The UI just provides a front end for the service. 

So really, it shouldn't ever see a high CPU usage like this.

ok will do - if its relevant i was connecting via RDP 

 

yes did have performance section open - default for me

 

just waiting on a Handbrake run to finish then will run troubleshooter - should only be 20 mins or so

 

update - just closed the performance section - cpu usage went to zero and stayed their!

 

update2 - on Win10 closing the performance section - also dropped the small cpu usage to zero

memory dump submitted

IIRC, the Performance counter section does increase CPU usage. 

 

And I've flagged the dump, so we can look into it.

Will do.
