When the entire WordPress multisite installation runs off a really tiny server, I have to use pretty much every single tip and trick I know in order to keep it on an acceptable performance level (while being secure).
These are the 4 techniques I used to optimize my WordPress installation.
- CDN (Cloudflare)
- Caching (WP Supercache)
If there’s anything that I missed out, please let me know and I’ll test it out.
