    I am facing two different problems when pressing  the export to PDF button external to the Kendo Grid (We are using : kendo.web.min v2015.2.624  and pako_deflate.min 2015.2.624 to enable compression in the PDF - we are using local data)
    1- The time it takes to export data to PDF is almost 10 times the excel export for the same set of data.
    2- Firefox is giving the warning dialog box (attached) that the script is unresponsive.

    Hello Brian,


    I have already answered the same question in the support thread that you opened, but I will copy my answer here as well:


    I am afraid that the issue is not a known one, nor is reproducible in our online demos, so please extract a runnable sample in a Kendo UI Dojo and we will be happy to help.


    As for the difference between the pdf and excel export generation - these two features are not related and cannot be compared performance wise.

    Hey @Kiril Nikolov the issue isnt reproducible because all the demo's you have dont export anything over 100 records if that. What about if I have 5,000 or 50,000 records(which are actual cases for me).

    Note that redrawing DOM objects in a PDF file is a big and heavy task. So the performance will depend on the browser and the actual user machine. If the delay comes with increasing the number of extracted records, then we can consider this as expected.
