Performance issue when idle

Hi,

I observe performance issue in idle state with SfDataGrid when FrozenColumnCount is higher than 0. In that case I can see CPU between 1-2% and continuous memory allocations when app is idle. 

When FrozenColumnCount is set to 0 then CPU is 0 and memory allocations are gone.

You can test it in attached sample.

Thanks

Hi Ondrej, 
 
Thank you for your interest in Syncfusion products. 
 
We could understand the use case that setting FrozenColumnCount as more than zero causes performance in CPU usage and could reproduce the reported scenario. We need some more time to analyze further with performance profiler and we will update you the proper details on 09th December 2021. 
 
We appreciate your patience till then.

Hi Ondrej 
 
From the analysis of performance profiler, the SfDataGrid does not seems to cause the CPU usage. So, please confirm the way that you are using to analyze the performance at your end. So that, we will analyze with that method and update you the details.

Hi,

from my observations it looks like some styling is causing high CPU - animation, progress bar, etc...

But it must be connected to SfDataGrid somehow if it can be controlled via  FrozenColumnCount property. Or what do you think is causing that?

I use JetBrains dotMemory profiler and there I can see constant memory allocation in heap generation 0:


This is of course connected to CPU and it is not normal behavior of idle application.

When comparing two snapshots I get that the memory allocations are happening on this path:

From that I infer that it is style connected issue.

Of course if I set  FrozenColumnCount to 0 then no memory allocations are happening and CPU is 0%.


Have a look on it please.

Hi Ondrej 
 
We need to get all the required software (JetBrains) to test the reported use case at our end. So, we need some more time to install and check the reported scenario. we will update you with proper details on 15th December 2021.

Hi Ondrej , 
We have checked the reported CPU usage using JetBrains profiler and we are able reproduce the same in our end..  We are in need of some more time to analyze the cause for the issue and we will update you with proper details on December 20, 2021.

Hi Ondrej ,  
 
We have analyzed the reported issue. We would like to let you know that we have achieved the frozen columns using the visual state. On further analysis we have found that the performance issue occurs due to the setting the visual state. While referring the Microsoft docs, we have found using the VisualState will cause the performance issue. Please refer the below msdn link  
 
 
Please let us know if you have any concerns.

Hi,

Its good to know you've found the cause of the problem. Is there a way how to improve your style and get rid of that CPU issue? I think there must be, the docs you are refering to mentions performance impact when there are animations used. But I don't see any animations in connection with frozen columns.

I've seen similar problem connected to animation on progress bar. In that case animations were using CPU even when progress bar was hidden - I believe this will be something similar.

I would realy appreciate if you could have a look on possible improvements in this functionality.


Thank you!

Hi  Ondrej, 
 
We have analyzed the scenario in our end. We have used the animation to increase the thickness of the frozen column border line. However, we have raised an MSDN query regarding the issue. Please find the github query link below. We will update you once we got solution from the Microsoft.

Hi,

I've checked the WpfApp1 sample from github link above. Seems that the problem is with Duration parameter. For some reason Duration="1" ​makes troubles. If you change it to Duration="0:0:1" or Duration="Automatic" ​or if you remove the parameter then CPU is 0. 

Check it out, please.


VS Vijayarasan Sivanandham Syncfusion Team January 5, 2022 03:42 PM UTC

Hi Ondrej Svoboda,

Based on provided information we are checking your reported scenario with the sample from GitHub. So, we need two more business days to validate this. We will update with further details on or before January 07, 2022.

We appreciate your patience and understanding.

Hi Ondrej,


We are still facing the issue from our side. We will fix this issue once we get a proper solution from the Microsoft.

OS Ondrej Svoboda January 7, 2022 03:02 PM UTC

Please have a look on attached sample - the only change there is that Duration property has been removed. Then the CPU problem is gone based on my observations.

I'll also post this info to the github issue you cretated. Maybe it will help them and speed up the solution.

I think better would be to use this kind of workaround, rather then wait for proper solution from Microsoft which I'm afraid can take a long time.

Hi Ondrej,


We have checked the work around but we are still facing the issue from our end. We will fix once we got a proper solution from the Microsoft. We appreciate your patience until then.

OS Ondrej Svoboda January 17, 2022 02:15 PM UTC

Hi,

do you have experience with Microsoft support in such cases? When do you think they will deliver some solution? I'm really sceptical about that.

In the mean time I've found that the same issue occurs when using FilterRowPosition="FixedTop". Please check.

Regards

Ondřej


OS Ondrej Svoboda January 17, 2022 02:26 PM UTC

Also please check this note on github: https://github.com/dotnet/wpf#net-framework-issues

Looks like this issue should be reported elsewhere...


Please don't feel offended, I'm just trying to get it fixed ASAP. Thanks.


SS Sampathnarayanan Sankaralingam Syncfusion Team January 18, 2022 02:17 PM UTC

Hi Ondrej,


We usually raise the query in the github and also have got a support from Microsoft to resolve the issue. We have also posted the query in the developercommunity also. We will fix the issue once we get the update for the Microsoft. We appreciate your patience until then.
