This page shows OneTrust under the throttled-mobile profile, which applies a 4× CPU slowdown, 1,638 kbps down, 750 kbps up and 150 ms of added latency to simulate slower conditions; it does not emulate a phone screen. Every load is cold, and each figure is the p75 of 20 loads in the run of 24 Sep 2026. OneTrust scored 54/100 (Poor) and ranked 11th of the 12 tested installations. The banner appeared in 2.7 s (time to banner) and the page transferred 206.8 KB more than the no-SDK control (bytes over the wire). It did not delay first paint (FCP) and added 166 ms of Total Blocking Time (TBT), and the banner covered 31.8 % of the first viewport (viewport coverage).
