FAQ
Common WordPress performance issues and short answers.
What causes high Time To First Byte (TTFB)?
Slow hosting, heavy plugins, or blocking database queries are common root causes.
Do too many plugins hurt performance?
Not by count alone, but poorly coded plugins can add heavy scripts and expensive queries.
How can I optimize images quickly?
Serve WebP/AVIF, compress aggressively, and lazy-load non-critical media.
Why does mobile performance score lower?
Mobile CPUs are slower; reduce JS payload and remove render-blocking resources.
Can my theme be the bottleneck?
Yes. Bloated themes often ship large CSS/JS bundles and unnecessary components.
How important is a CDN for WordPress?
A CDN cuts latency globally and offloads static files from your origin server.
What database tuning helps most?
Clean autoloaded options, add missing indexes, and remove stale transients regularly.
Which metrics should I monitor weekly?
Track Core Web Vitals, TTFB, error rate, and cache hit ratio for trends.
