How to improve rendering the DOM performance on IE11

[Sayed]

I am rendering big array of data in table element in my Confluence plugin
The plugin allow the user to filter the data, and when a filter used an Ajax request will be send with the filter to the back-end to get the new data.

Replacing the old tbody tag with new one which's represents the new data takes about 19 seconds on IE11, while it takes about 350 ms on Chrome.

The length of the array of data is about 1700.
