Guidance around complimentary caching plugins

    Enabling NGINX cache and using this plugin sounds like a great way to improve performance and reduce load on my server.

    But I also have other caching solutions in place closer to the application, namely WP Super Cache.

    Since the cache the plugin manages is at a higher level in the stack, are there any known compatibility issues with caching plugins that users should be aware of?

    If you use WP Super Cache or similar in combination with this plugin, are there any gotchas or recommended configuration to be aware of?

    I never tried using WP Super Cache or similar with the plugin, however I’d assume it would be fine. I assume that NGINX would cache the files that WP Super Cache has generated, instead of directly what WordPress has generated.

    However, I think that it’s unnecessary, because from my understanding, NGINX caches the HTML, CSS, JS, etc. that WordPress has generated. As far as I know, WP Super Cache does that too, except it uses Apache’s .htaccess file to configure caching. Maybe using something like Autoptimize could help with performance though, as this would defer JavaScript.

    I might be wrong though.

    Do not use WP Super cache in combination with the plugin above. It doesn’t make sense.

    Redis cache will still help the performance.

    Also any tools to optimise css and js files will also help the preformace

    @jaapmarcus are you sure WP Super Cache isn’t complimentary to NGINX caching?

    Some places that suggest it may be:

    Nginx website doesn’t talk about combining both

    If 99% of the content allready cached with fastcgi caching why should I also need to cache the last 1%?

    It will also mean more stress on your hard drives as the cached content is stored multiple ways and it is even possible the plugin decreases the performance due to certain changes…

    I have been running multiple websites Hestia en cacheing enabled and never had to fallback again to any caching plugin in.

    For 1 website I use:
    https://github.com/jaapmarcus/wp-nginx-purge

    Based on ngx_http_cache_purge module it works great but it also requires a lot of more work.. How ever it has slightly more “advangtages” as you can delete only one cached page except everything…

    Thanks, I’ve removed the WP Super Cache layer and performance does feel about the same.
