nsgoyat Thanks again. I don't know what we're doing wrong, but FastCGI didn't do anything for us, we were suffering from downtime and server load of 90+ on a 16 core server. 🤦♂️ I also don't know where/how FastCGI caches?
Only when I switched to wpredis the load went down and got the website back operational.
Based on this, my next step improvement consideration is whether I should keep Redis object caching on, but switch to WP Rocket for the site: --wprocket and whether this will be an improvement on the existing setup?
Also another thing I read here, somebody said 'backend' caching is better than leaving the caching to a 'plugin' (like WP Super Cache), so my understanding is WP Rocket caching is all done using the plugin/php which means more load?
Thanks for any clarification on this.
