Some Pagespeed Score Problems

Use WebP always as it is better both than JPEG and PNG.

  • All in all, I’d say that google’s claims are valid - it’s a compression schema that does seem to outperform jpg.

Fix shit with:


Noviteti pagespeed: https://developers.google.com/speed/pagespeed/module/release_notes

Preload, AMP

  • Redis Support?
  • Allow combining stylesheets with IDs (done)
  • Add preload hints (coldn’t detect them)
  • Maybe some workable AMP - Minimal AMP support: don’t invalidate AMP (done)
  • Configures the length of time the prioritize_critical_css beacons are valid.
  • Set s-maxage

This also is at the end done and rewritten

https://github.com/pagespeed/ngx_pagespeed/issues/1304 woow? the reason was: “

not minifying?

Hm, that is odd. If I request this page from the command line (using curl), I get the fully minified/rewritten version, if I do it from Chrome, I get the non-minified version (as you mentioned).

Confirmed, this is User-Agent-dependant:

Disabling domain re-writing to CDN fixes it?

Maks, n.css does contain @import (in a comment). That’s why they are not combined.


1: PNG

They are at the end converted to WebP, so this is not problem

Well, finally fixed when I disabled pagespeed totaly for svg!

It was something in gzip.conf but I also had browser cache so changes were not propagated, and therefore I was confused.

I finally get it! SVG in pagespeed is not treated as other images so filter like extend_cache (signing URLs with a content hash to bust cache). https://github.com/pagespeed/mod_pagespeed/issues/1221 So for the SVG, until automated, you must do it manually, signing it by modification date.

using PHP filemtime but for now - I won’t do it.
