Description: Loading the W3C SVG example car.svg is slow in LibreOffice, and the export to PDF is also slow. Each of these take ~10 seconds. The same file is loaded immediately in Firefox and Chrome. On debug builds of LibreOffice, it is ~1 minute. Steps to Reproduce: 1. Download this example from w3.org website: https://dev.w3.org/SVG/tools/svgweb/samples/svg-files/car.svg 2. Open it in LibreOffice using "Open File" 3. Export it to PDF Actual Results: The loading is slow, and the interface becomes non-responsive for some seconds. In the official release build, it takes ~10 seconds to become responsive again. Export to PDF also takes ~10 seconds. On debug builds of LibreOffice, it is ~1 minute. Expected Results: The file should be loaded immediately (<1s) and the UI should be responsive.

Could you please compare the output for these on your machine? $ time libreoffice7.2 --headless --convert-to pdf car.svg $ time google-chrome --headless --disable-gpu --print-to-pdf car.svg
Opens very fast with master of Linux 7.4 bibisect repo (similar results for all VCL backends) real 0m2,946s user 0m2,820s sys 0m0,166s Tested with export OOO_EXIT_POST_STARTUP=1 PDF export time: real 0m5,548s user 0m5,330s sys 0m0,240s Same with oldest of Linux 6.3 repo Chromium time: real 0m1,468s user 0m0,211s sys 0m0,196s I guess we can set to NEW, then. You can disregard the debug build times as they will always be slow.
