Hallo,
we use grids with many columns and these are rendered really slowly. Even with no rows this takes up to 20 seconds. I posted the config script of such a slow grid and an internet explorer 11 (~20 seconds) and a chrome (~5 seconds) profiler file. Please have a look at these reports. Do you have an idea how to speed the rendering up?

Hello,
Thank you for posting into Infragistics community!
I did a review on your configuration and I would suggest referring to the following topic
If you are having a lot of columns you should use the filtering feature with advanced mode, because in the simple one there are filtering editors for each column and this has a performance impact on the rendering.
thanks for your hint, disabling Filtering renders the grid much faster. Using filtering in simple mode is really comfortable, but we will discuss using filtering in advanced mode for big grids.
Great, please let me know if there is a need of further assistance with this one.
well, our customers don't like advanced filtering, because simple filtering is much easier to handle. It would be great if you do some performance tuning on simple filtering :) .
The greater amount of filtering editors is really the root cause so any way to reduce them will be an improvement of the performance. It would be great to find the columns, which won't be filtered or don't make sense to be filtered and then disable filtering for them.
