Here seems to be a fairly confident +50ms regression on page load time (at the 75th percentile).
Found through navtiming-loadEventEnd, but also seen under:
- navtiming-domComplete (same amount: ~ +50ms)
- mediaWikiLoadEnd (more affected: ~ +80ms)
- navtiming-processing (same amount: ~ +50ms)
See also https://wikitech.wikimedia.org/wiki/Performance/Metrics#navtiming-2_metrics for the definitions of these metrics.
