I'm experiencing high initial server response time on my WordPress website, even though I'm using a powerful server setup and have applied multiple optimization strategies.
Server & Configuration Details:
- Server Specs: 8 Cores / 16GB RAM (aaPanel + NGINX)
- PHP Version: 8.3.21
- MySQL: v5.7.44
- Web Server: NGINX 1.24.0
- OS: Linux
- PHP Memory Limit: 512M
- PHP Max Input Vars: 1000
- PHP Max Post Size: 50M
Optimization Steps I've Taken:
- Installed OPcache extension
- Configured Redis with Object Cache Pro (working fine)
- Using Cloudflare free plan (DNS + CDN)
- Installed and using the following plugins:
- Elementor (3.29.1)
- WooCommerce (9.8.5)
- Object Cache Pro (1.23.1)
- WP Fastest Cache + Premium (1.3.7 / 1.7.2)
- Slider Revolution, Facebook for WooCommerce, etc.
- Hide My WP Ghost, YITH WooCommerce Compare, and others
I’ve also tried disabling some plugins to see if any were causing the issue, but it didn’t make a noticeable difference. Everything seems to be configured properly, but the initial server response time remains high.
Could this be due to a server misconfiguration or something I’ve missed?
Any advice or suggestions would be greatly appreciated.
