jmarantz commented on issue #1685: Pagespeed causes high FTTB on nginx URL: https://github.com/apache/incubator-pagespeed-ngx/issues/1685#issuecomment-613163035 So the Cache-Control at origin -- that is, with pagespeed in standby, is empty? In that case the CDN might be configurable as to whether it would cache HTML by default, and for how long. You might be able to control that behavior at the CDN. If the CDN is caching your HTML, it's going to significantly improve the TTFB obviously. You can also achieve this with PageSpeed via its downstream caching feature, but how to do that is dependent on the downstream cache, and PageSpeed only documents the flow for Varnish. https://www.modpagespeed.com/doc/downstream-caching On Mon, Apr 13, 2020 at 7:54 PM Jake Edwards <notificati...@github.com> wrote: > The Cache-Control is dictated by the Pagespeed module.
