Export to PDF of Pages Containing Roadmap Planner Macro Slow to Complete

Summary

Exporting Confluence Pages containing a Roadmap Planner Macro are slow to complete

Environment

5.9.0-OD-55

Steps to Reproduce

1. Create a page and add the Roadmap Planner Macro and using the Example data provided
2. Export to PDF using Content Tools Export
   • It cannot be exported using Tools > Export to PDF due to it taking more than 60 seconds to complete.

Expected Results

Per the Workaround in CONF-19815 to utilize the Space Tools Export to PDF of larger pages, the page should export to PDF within a few minutes like other pages

Actual Results

Just using the example data on the Roadmap Planner Macro, it takes ~10-15 minutes for the Export to PDF to complete.
If there is more data, it will take much longer; for instance, a Roadmap Planner Macro consisting of 4 Lanes and 30 Bars takes 60-90 Minutes to Export to PDF

Due to the length of time it takes to export, a user may experience a session disconnect while they wait for the export and would not be able to collect the file

Notes

Exporting to HTML of the same page takes only a few minutes
