Why does it say "Generated in X seconds" in my PDF?

When Debug Mode is enabled in the global PDF settings, Gravity PDF will show debug information at the bottom of the PDFs it generates (PDF stats). This may look like:

Generated in 1.13 seconds Peak Memory usage 64.00 MB Number of fonts 3

This is useful information when building a custom PDF template, but not something you'll want enabled during production. You can disable this by toggling off Debug Mode.
