1675138 - Enforce CRLite in Desktop Nightly

Status: RESOLVED FIXED

(Core :: Security: PSM, task, P1)

Description

[J.C. Jones [:jcj] (he/him)]

We have ~10 months of CRLite telemetry-mode data in both Beta and Nightly, and about 2 months with data that has been kept up-to-date, and that telemetry agrees with our end-of-2019 experiment that CRLite should indeed speed up versus OCSP.

To confirm, we should enable the Enforce mode for Nightly users; that will stop collecting the CRLITE_FASTER_THAN_OCSP_MS and OCSP_FASTER_THAN_CRLITE_MS but should cause an improvement in SSL_TIME_UNTIL_READY as a weighting of the CRLITE_FASTER_THAN_OCSP_MS vs the percentage of cache-miss first page loads: we expect it'll mostly affect the outliers.
