osano
Vendor CDN script
This page shows Osano 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. Osano scored 72/100 (Fair) and ranked 7th of the 12 tested installations. The banner appeared in 1.7 s (time to banner) and the page transferred 78.2 KB more than the no-SDK control (bytes over the wire). It delayed first paint by 840 ms (FCP) and added 13 ms of Total Blocking Time (TBT), and the banner covered 24.2 % of the first viewport (viewport coverage).
