Are there any performance issues with viewportRowRenderingOffset

[rohit.parwal]

Hi Team,

we have a grid of 50 columns and 30K rows, we are also using 4 custom renderes for 4 columns. For one of the requirement, we had to use viewportRowRenderingOffset: 50, because we wanted to load all columns before hand. Is there any performance issue we could see due to use of viewportRowRenderingOffset.

thanks

Hi @rohit.parwal

You shouldn’t have any performance issues by loading 50 x 50 while initialization. Here is a demo http://jsfiddle.net/fgupq6rq/ that uses the following settings and it has a slight delay at the beginning, however, it takes around 1.5 seconds (on Chrome 60/Windows 10) and after that scrolling is smooth.
