- Loading method
This script downloads in the background and runs after the HTML is parsed, so the browser can draw the page’s first visible content without waiting on it.
- Script filesize
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 +261 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 +261 ms stacked on top of your other assets, because much of the work overlaps parallel downloads.
