ShadowXVII edited a comment on issue #1685: Pagespeed causes high FTTB on nginx URL: https://github.com/apache/incubator-pagespeed-ngx/issues/1685#issuecomment-613142726 ### Timings @Lofesa , re: TTFB, I wasn't clear with my timings -- the full details are provided by Chrome which the lionshare of that figure is TTFB in my scenario. No Pagespeed in URL (standby)  With PageSpeed (?PageSpeed=on&PageSpeedFilters=%20debug)  ### Cache I think Cache Control might be the culprit here (or rather, is causing it to look like PageSpeed). @jmarantz , I'm not sure -- [the documentation is ambiguous](https://docs.microsoft.com/en-us/azure/frontdoor/front-door-caching#cache-expiration) -- It says "assets" are cached, but doesn't mention HTML output. The origin request is to a Wordpress website, backed by redis. Maybe I can use some cache control headers to bypass the CDN temporarily to verify the behaviour?
