    We are using the PDFExport component to generate a PDF version of our report, which consists of 128 components with a mixture of HTML tables and chartjs outputs. On chrome the report generates, however it takes around 1 minute due to the sheer number of components we have. The final page size is 59 pages and is just under 1MB in size

    When we try and use the same logic inside IE11,the report never downloads and we can see the CPU go up to 100%. Are there any options we can use with the PDFExport component to try and increase the performance?

    Hello, Chris,

    In cases, where the PDF file is a large one we suggest using server side export:

    https://www.telerik.com/kendo-react-ui/components/drawing/limitations-browser-support/#toc-general-behavior

    "The maximum file size of the exported PDF document has a system- and browser-specific limit—use a server-side solution for large documents."

    One option is to convert the PDF to a base64 string and send it to the server for export:

    https://www.telerik.com/kendo-react-ui/components/pdfprocessing/base64string/

    Also, please have in mind that have the reporting product, which is especially made to generating large reports:
