Wordpress Which plugins to use for better performance for Wordpress?

All the performance and page speed Wordpress plugins you need will be found in Centmin Mod 123.09beta01 and higher's default centmin.sh menu option 22 Wordpress auto installer routines. See https://community.centminmod.com/th...l-vs-centmin-sh-menu-option-22-install.15435/ and example live Wordpress blog of mine at https://servermanager.guide/ and Centmin Mod Wordpress install guide at https://servermanager.guide/122/how-to-install-wordpress-on-centmin-mod-lemp-stack-guide/.

In context of Wordpress caching for centmin.sh menu option 22 wordpress auto installer for Centmin Mod 123.09beta01 and newer, you have 3 offered wordpress caching options:

1. Redis Nginx Level Caching - centmin.sh menu option 22 will auto install redis if not detected if you choose this in centmin.sh menu option 22 setup. Otherwise, need to install redis yourself. Best combined with Autoptimize WP plugin + Autoptimize Gzip companion plugin
2. KeyCDN Cache Enabler for full page static html caching (safest choice for balance of performance and reliability). Best combined with Autoptimize WP plugin + Autoptimize Gzip companion plugin
3. WP Super Cache for full page static html caching. Best combined with Autoptimize WP plugin + Autoptimize Gzip companion plugin
4. PHP-FPM Fastcgi_cache full page static HTML guest cache in private development as of writing so not available yet. Best combined with Autoptimize WP plugin + Autoptimize Gzip companion plugin

Code (Text):

Default is to install KeyCDN WP Cache Enabler Plugin as it is more
stable and reliable than WP Super Cache and Redis Cache.
Redis cache may have issues with caching due to long 6hr cache TTL
Fastcgi_cache (PHP-FPM) will have best performance
You can select which caching method to use below:

--------------------------------------------------------
Wordpress Caching
--------------------------------------------------------
1) KeyCDN Cache Enabler
2) Redis Nginx Level Caching
3) WordPress Super Cache
4) Fastcgi_cache (PHP-FPM)
--------------------------------------------------------
Enter option [ 1 - 4 ] 4

you selected option 4 (Fastcgi_cache PHP-FPM) [wpscache=fastcgicache]

1. Both PHP-FPM fastcgi_cache and Redis Nginx level caching can be fastest but needs fine tuning and deep understanding of your web app and it's plugins to get right i.e. woocommerce etc. So can be problematic too. Most caching is are for guest caching only.

2. keycdn cache enabler wp plugin - better version of wp super cache for full page static caching of wordpress. Least problematic and closest to set and forget with maybe some tuning needed depending on wp plugins and site configuration. Config is for guest caching only. Highly recommended, if you just want a Wordpress cache method that just works without headaches.

And regardless of caching method, having right server(s) hardware and configuration and LEMP stack and system TCP level configurations to handle the traffic is a must otherwise regardless of caching used, it won't scale. So you would want non-OpenVZ based VPS like KVM or dedicated. Choosing OpenVZ VPS will limit your scalability.

FYI, all caching methods = generally higher memory consumption and sometimes higher cache related cpu consumption. The goal of caching in context of wordpress is usually to lessen the load placed on php/php-fpm as that is the weakest part of any LEMP/LAMP setup in terms of scalability. So sometimes caching isn't necessary faster just scales better in high concurrent traffic environments.

You can see centmin.sh menu option 22 wordpress installed demo and benchmarks on my Wordpress7 demo site with Redis Nginx level cache + Cloudflare and live Wordpress blog at https://servermanager.guide/ with PHP-FPM fastcgi_cache + Cloudflare.

 

Yes if you can get Cloudflare Worker caching working it does wonders. Testing on https://servermanager.guide/ right now too for my own private use.

Interesting haven't heard of that one yet. Thanks for sharing ! However, concern is requiring your Cloudflare account wide API key can be security issue as it gives access to all your CF acccounts' web sites. It's better to use Cloudflare's new API token keys which can be restricted to specific Cloudflare features and sites/zones and not entire Cloudflare account.

Autoptimize will always help especially 2.6+ has image lazy load support too. I switched https://servermanager.guide/ from Google Native lazy loading (manually added to functions.php) to Autoptimize 2.6+ enabled lazy loading as well. So far looking good https://community.centminmod.com/th...ermanager-guide-journey-for-page-speed.19108/

 

see WP Cloudflare Super Page Cache

 

it's due to the criteria coded by Google as to when to lazy load and when not to and it's dependent on internet speed detected by visitor i.e. mobile detected speeds will load all images within first 3000px vertical pixels which is to lengthy !

I also switched from Google native lazy load via functions.php edit to Autoptimize 2.6+ lazy load via lazysizes for my Wordpress blog at https://servermanager.guide/
