WordPress Site Speed — What We Check First

A slow WordPress site almost always comes down to the same 4-5 causes. Before you blame plugins, check these in order.

1. Hosting — rule it out first

On shared hosting, one resource-heavy neighbor is enough to slow down the whole server. If TTFB (Time to First Byte) is above 600ms on an empty page, hosting is the problem — not the theme, not a plugin. We move clients onto RE:HOST’s (rehost.ge) VPS plans, where TTFB usually lands at 100-150ms.

2. Images — the biggest single win

A 10MB JPG uploaded straight from a phone is often the single reason a page takes 5+ seconds to load. What actually fixes it:

• WebP/AVIF conversion — 60-80% smaller with no visible quality loss.
• Lazy loading on everything below the fold.
• Correct width/height attributes — prevents layout shift (CLS).

3. Plugin count vs. plugin quality

30 well-written plugins aren’t a problem. 5 badly-written ones can bring a site to a crawl. We audit each one with Query Monitor — if a plugin fires 200+ database queries on a single page load, it gets replaced or removed.

4. Caching — three layers, not one

• Page cache (WP Rocket, LiteSpeed Cache) — skips re-running PHP on every request.
• Object cache (Redis/Memcached) — caches database queries.
• CDN (Cloudflare) — serves static files close to the visitor.

Turning all three on together usually cuts load time from 3-4 seconds down to about 1 second.

5. Core Web Vitals — what Google actually measures

LCP (Largest Contentful Paint), INP (Interaction to Next Paint), and CLS (Cumulative Layout Shift) directly affect Google’s ranking. A site that scores poorly here loses in search results, not just in visitor experience.

What we see on real projects: correctly configured hosting, caching, and image optimization typically cut load time by 60-70% — without touching a line of custom code.
