Transfer is the compressed download size, and decoded is what the browser parses afterward.
What this means for your site
On our empty test page, the load event finished +231 ms later with the tag installed. On a real site, page load is likely to take at least that long — but usually not the full +231 ms stacked on top of your other assets, because much of the work overlaps parallel downloads.
