Configuring caching for faster page loads

Wordpress

Enable caching plugin like WP Super Cache or use built-in caching

Serves static HTML files reducing PHP and database load, speeding up page delivery.

📈 Performance GainReduces server processing time by up to 80%, improves LCP significantly

Configuring caching for faster page loads

Wordpress

No caching plugin or caching disabled in settings

Every page request generates full PHP processing and database queries, slowing down response time.

📉 Performance CostBlocks rendering for 200-500ms on each page load

Performance Comparison

Pattern	DOM Operations	Reflows	Paint Cost	Verdict
No caching	High (dynamic content on each load)	Multiple reflows per page load	High paint cost due to slow HTML delivery	[X] Bad
Caching enabled	Low (static HTML served)	Single reflow	Low paint cost with fast HTML	[OK] Good
All scripts loaded upfront	Medium (many scripts parsed)	Multiple reflows if scripts modify DOM	Medium paint cost	[!] OK
Selective script loading	Low (only needed scripts)	Single reflow	Low paint cost	[OK] Good
Large uncompressed images	N/A	N/A	High paint cost due to large images	[X] Bad
Compressed and lazy loaded images	N/A	N/A	Low paint cost, deferred loading	[OK] Good
