WordPress Too Slow? 7 Reasons Why & The Permanent Fix
If you're searching for "why is my WordPress site so slow" or "how to speed up WordPress," you're not alone. WordPress performance issues affect over 60% of all WP sites, and the solutions are often temporary band-aids rather than real fixes.
In this comprehensive guide, we'll explore:
- Why WordPress is inherently slow
- Common "fixes" that don't actually work
- The permanent solution that can make your site 10x faster
Quick Answer: Why Is WordPress Slow?
TL;DR: WordPress is slow because it's PHP-based, database-dependent, and requires processing every page request dynamically. No amount of caching plugins can fully solve these architectural limitations.
The permanent fix? Migrate to a static site generator like Next.js or Astro — and we have a free tool that does it in 5 minutes.
7 Reasons Your WordPress Site Is Slow
1. PHP Processing on Every Request
WordPress runs on PHP, which means your server has to:
1. Receive the request
2. Load WordPress core (~2000+ files)
3. Load your theme
4. Load all active plugins
5. Query the database
6. Build the HTML
7. Send the response
This happens on every single page view. Even with caching, the initial build and cache invalidation create bottlenecks.
Static sites like Next.js: Generate HTML once at build time. Serve instantly from CDN. No processing needed.
2. Database Queries for Everything
WordPress stores everything in MySQL:
- Posts and pages
- Comments
- Options and settings
- Plugin data
- Theme customizations
A typical WordPress page makes 10-50 database queries. Even with Redis or Memcached, this creates latency.
Static sites: No database at all. Content is compiled into the HTML files.
3. Plugin Bloat
The average WordPress site has 20+ active plugins. Each plugin:
- Adds PHP files to process
- May add database queries
- Often loads its own CSS/JS files
- Can conflict with other plugins
Common problematic plugins:
- WooCommerce: Adds 10+ database tables
- Yoast SEO: Adds meta queries
- Elementor: Adds heavy inline CSS
- Contact Form 7: Loads JS on every page
4. Shared Hosting Limitations
Most WordPress sites run on shared hosting ($5-15/month), where:
- CPU is shared with 100+ other sites
- RAM is limited
- PHP workers are restricted
- Database connections are capped
Modern static hosting (Vercel, Netlify): Free tier, global CDN, unlimited bandwidth, instant scaling.
5. Heavy Themes
Premium WordPress themes like Avada, Divi, or Elementor Pro:
- Include hundreds of unused CSS rules (400KB+)
- Load jQuery + multiple libraries
- Have complex PHP template hierarchies
- Include page builder bloat
6. Unoptimized Images
WordPress doesn't optimize images by default. Users upload 5MB photos that are:
- Served without compression
- Not converted to modern formats (WebP, AVIF)
- Loaded all at once (no lazy loading)
7. Lack of Modern Caching
Even with caching plugins like WP Rocket or W3 Total Cache:
- Cache gets invalidated frequently
- Logged-in users bypass cache
- Dynamic content breaks caching
- First-time visitors always hit uncached pages
Common "Fixes" That Don't Actually Work
❌ Install a Caching Plugin
Caching plugins help but don't solve the root cause. Your server still runs PHP, and cache misses are slow.
Reality: You'll see 30-50% improvement, not 10x.
❌ Upgrade to Better Hosting
Moving from $5/month shared hosting to $50/month managed WordPress hosting helps, but:
- You're still running PHP
- Database queries still happen
- Plugin bloat remains
Reality: 40-60% improvement at 10x the cost.
❌ Use a CDN
A CDN (Cloudflare, etc.) helps with static assets but:
- Dynamic HTML still comes from origin
- Cache headers need proper configuration
- WordPress admin often bypasses CDN
Reality: 20-30% improvement for returning visitors.
❌ Remove Unused Plugins
Helps marginally, but:
- Core plugins (SEO, forms, security) are still needed
- Theme bloat remains
- WordPress core is still slow
❌ Optimize Database
Running OPTIMIZE TABLE helps briefly, but:
- Tables get bloated again
- Autoload options accumulate
- Post revisions pile up
The Permanent Fix: Migrate Away from WordPress
The only way to truly fix WordPress speed issues is to remove the bottleneck entirely — WordPress itself.

FAQs
Will I lose my Google rankings?
No. We preserve your URL structure exactly and generate proper 301 redirects. Most migrated sites see improved rankings due to better Core Web Vitals.
Do I need coding experience?
Not at all. Our tool generates a complete, working site. Just download and deploy.
How much does it cost?
LeaveWP is 100% free and open-source. Hosting on Vercel is also free for most sites.
What if I need to edit content later?
You can either:
1. Edit MDX files directly (simple text files)
2. Use a headless CMS like Payload or Sanity
3. Keep WordPress as a backend (headless mode)
Conclusion: Stop Fighting WordPress
You can spend hours:
- Testing caching plugins
- Upgrading hosting
- Optimizing databases
- Minifying CSS/JS
Or you can spend 5 minutes migrating to Next.js and get a site that's genuinely 10x faster.
