What is the best caching solution for WordPress ?

There is no "best solution", because there are benefits/disadvantage for each caching solution and it depend on your usage.

Here some informations :

Cache backend command argument description
fastcgi_cache --wpfc the simplest solution, because it do not rely on any plugin excepted nginx_helper used to purge cache after content updates
redis-cache --wpredis powerful solution which support multi-server setup and it provide full-page cache in redis via Nginx + object-cache via Redis-Object-Cache plugin (also used to purge cache)
wp-super-cache --wpsc basic solution based on a plugin which create and serve static html files.

Does WordOps support WP-Rocket ?

At the moment, WP-Rocket works properly on WordOps but do not receive any performance boost from our Nginx configuration. We are going to work on it and to provide additional Nginx configurations for WP-Rocket.

Why do I get warning from my web browser when opening WordOps backend ?

At the moment, WordOps backend is secured with a self-signed SSL certificate, which provide the same level of encryption than any other certificate but do not come from a certificate authority. Your Web browser only warn you about the fact that the certificate wasn't issued by a trusted certificate authority. We are already working on adding the ability to secure WordOps backend with a letsencrypt SSL certificate.

Does Nginx-wo support TLSv1.3 ?

No, currently our custom Nginx package isn't built with OpenSSL 1.1+ and Nginx-wo only support TLSv1.0 TLSv1.1 and TLSv1.2.

Why gzip compression is disabled by default ?

We disabled gzip compression by default due to gzip related security issues when using TLS connection. More informations here BREACH CVE. We replaced gzip by brotli, which provide better performance and compression than gzip.

Is WordOps Let's Encrypt stack compatible with Cloudflare CDN ?

WordOps Let's Encrypt stack is compatible with Cloudflare CDN, but we still have an higher failure rate when issuing SSL certificates on domains under Cloudflare CDN. We are working on it and we will keep you update as soon as we find a workaround to this issue.
