Grid initialization slowdown up to 20 times (with options enabled)

[Max]

Hello,

We have a few grids on a page with "filterable: {mode: row}" enabled. This option causes to render a single grid ~700-1000 ms, without this option it takes 10-20 times faster.

Here is example that demonstrates the issue

 

https://dojo.telerik.com/ebavEhos

 

First grid filterable option enabled, the second grid option is not set.

Below the grid, you'll see the time to init each grid.

 

Are there any ways to improve that performance?

 

Thanks,

Max

Hello, Max,

Thank you for the example.

The difference in the rendering mainly occurs because, with the row filter, the Grid is creating an AutoComplete widget for every column. In cases like this where the columns are many, creating 10+ additional widgets which is causing the additional delay.

If the performance is not acceptable we can suggest the other filter mode which will not make additional widgets on load and it will speed the performance.

We will still make more researches if the performance with filter mode row and a large number of a column can be optimized. If there is an optimization approach we will share it here for better visibility.

Hi Stefan,

 

Thank you for a response.

Looking forward to seeing performance optimization approaches if any.
