I run some of the performance tests from https://extensions.xwiki.org/xwiki/bin/view/Extension/PDF%20Export%20Application/#HPerformance and:

  • The new image seems to handle well 1500 print pages
  • I noticed an increase in the time it takes to generate the PDF (e.g. for 1500 print pages the increase is from ~5 minutes to ~6 minutes, so around 20% increase), but I didn't do multiple iterations. The increase could be caused by:
    • the extra processing we're doing to:
      • replace colspan and rowspan
      • auto-scale tables
    • the generation of PDF outline (bookmarks) which for 1500 print pages is big enough
    • the generation of tagged (accessible) PDF

I run some of the performance tests from [ https://extensions.xwiki.org/xwiki/bin/view/Extension/PDF%20Export%20Application/#HPerformance ] and:
* The new image seems to handle well 1500 print pages
* I noticed an increase in the time it takes to generate the PDF (e.g. for 1500 print pages the increase is from ~5 minutes to ~6 minutes, so around 20% increase
, but for smaller exports it's more around 10% or lower ), but I didn't do multiple iterations. The increase could be caused by:
** the extra processing we're doing to:
*** replace {{colspan}} and {{rowspan}}
*** auto-scale tables
** the generation of PDF outline (bookmarks) which for 1500 print pages is big enough
** the generation of tagged (accessible) PDF
