Increased Server Response Time

    Hi Frank,

    This plugin is fantastic and the way you run it is very professional – you are a WordPress superhero. Thank you!

    I do have a minor issue optimizing our website. Turning Autoptimize on will improve the scores on GTMetrix and Page Speed Insights. However if I open the page in Chrome or Firefox, load times are as long as 8-12 seconds. This doesn’t happen all the time, sometimes it loads nicely. If I refresh (in incognito mode) then consecutive loads are mostly fast. Cause of this slowness seems to stem from getting an initial response from the server.

    Any help is much appreciated.

    Sorry for disappearing! Was busy…

    One thing I forgot to mention is that turning speedupper off will break site CSS. Font Awesome and column structure both stop working for example.

    First byte times:
    * AO 2.2.2 CSS only, speedupper off, “Also aggregate inline CSS?” disabled: 1.9s

    I’m going to need more detailed instructions for adding the abovementioned flag. Where in options.php would I need to add it and what’s the exact syntax. Currently there aren’t any autoptimize related code in there that I can detect.

    So I’m exchanging 0.2s for better form – is it worth it? Google seems to think that 0.2s is the maximum tolerable first byte time.

    Taking 1.6s+ for first byte seems awful. And that’s with a caching plugin. Any suggestions on how to track down what is causing this? Or are WP sites just slow by nature?

    Tried turning on JS and HTML but not CSS with latest version of AO. This config seems to reduce first byte time to 0.7s. Can this make sense?

    Also, when testing with any configuration first byte times vary greatly. With AO off, for example, it’s sometimes 1.6s and sometimes 0.7s. Do you know what is causing this instability?

    OK, this could be due to a bug which I fixed recently on the development-version. the fix is adding one questionmark in AO’s code, as explained here. if you’re up to that try that fix, it might solve these problems.

    Where in options.php would I need to add it and what’s the exact syntax. Currently there aren’t any autoptimize related code in there that I can detect.

    you don’t have to edit options.php, but go to /wp-admin/options.php in your browser, which is a (long) page with all options used in your site. in that list you’ll find autoptimize_css_justhead for which you have to update the value to on

    Taking 1.6s+ for first byte seems awful. And that’s with a caching plugin.

    1.6s with caching plugin if the page cache is empty would be OK, but if TTFB stays that high even if the page is in cache, then you have a page caching problem. consider experimenting with another page caching plugin to see what happens?

    well, that confirms the problem is with CSS optimization, yes.

    possibly you’re on a shared server and the load gets higher? but is that with or without page caching? because with page caching, assuming the page is in cache, even 0.7s is too high ..
