My WordPress Settings

---

This page shows details of my WordPress setup in order to get perfect performance.

For security reasons, some settings/plugins will not be disclosed.

Server

My servers are fully dockerized, so your deployment case may vary.

CDN

A long-term Cloudflare customer.

Docker Images

Service	Image
Proxy	custom-built caddy server. Caddy can automatically obtain SSL certificates, provide HTTP/2 and many more features than NGINX and Apache.
Database	mariadb. Believe it or not, MariaDB is faster than MySQL on my server.
WordPress	wordpress

Caddy Configuration

:443 {
    ... # some private config
    ... # proxy settings

    # Remove unnecessary headers
    header {
        -X-Powered-By
        ... # some private config
    }

    # Rewrite images to webp
    @acceptsWebp {
        header Accept *image/webp*
	    path_regexp webp ^(.+)\.(jpg|jpeg|png)$
    }
    handle @acceptsWebp {
        try_files {re.webp.1}.{re.webp.2}.webp {re.webp.1}.{re.webp.2}
    }

    # Bloack some accesses
    @forbidden {
        path /xmlrpc.php
        path *.sql
        ... # some private config
    }
    respond @forbidden 404
}

PHP Rewrite

This upload.ini removes the PHP upload settings defined in the image, which is annoying.

Map location: upload.ini:/usr/local/etc/php/conf.d/uploads.ini

file_uploads = On
memory_limit = ???M
upload_max_filesize = ???M
post_max_size = ???M
max_execution_time = ???

WordPress Plugins

Plugin	Reason
Autoptimize	Tried a lot, only this one can provide the best optimization performance for my case. Many others even slow down the loading speed
Code Snippets	Add PHP code snippets without changing PHP files.
Disable Comments	Sometime I need silence.
EWWW Image Optimizer	Image optimizer and webp converter.
LuckyWP Table of Contents	The best table of contents plugin I can find. No stupid JQuery, no stupid premium, no stupid CSS. FREE!!!
Polylang	Multilingual
Prismatic	Syntax hightlighter, even though sometime it is not working as you can see above 😔
Remove jQuery Migrate	GET OUT OF MY SITE.
Simple Local Avatars	No third-party Gravatar.
SmartCrawl	SEO
Two Factor	SECURITY, SECURITY, SECURITY.
WP Statistics	No Google Analytics.

Conclusion

With all these optimizations, this post page and the index page get both A on GTmetrix. Details can be found here and here.
