How to Speed Up Your Website on DreamHost: Complete Optimization Guide 2025
Website speed directly impacts user experience, conversion rates, and SEO rankings. Google uses page speed as a ranking factor, and users abandon sites that load slower than 3 seconds. Fortunately, DreamHost provides excellent tools and infrastructure for fast websites—when properly configured.
This comprehensive guide covers every optimization technique to maximize your DreamHost website speed, from basic configurations to advanced performance tuning, achieving Google PageSpeed scores of 90+ and load times under 2 seconds.
Understanding Website Speed
What Affects Page Load Time?
Server Response Time (TTFB):
- Time Dream Host server takes to respond
- Affected by: Hosting plan, server load, location
- Goal: Under 600ms
File Sizes:

Step 6: Optimize WordPress Database
Database bloat slows queries and increases load time.
WP-Optimize (Recommended):
Install
- Plugins > Add New > "WP-Optimize"
- Install and Activate
Optimize Database
- WP-Optimize > Database
- Check all optimizations:
- Remove post revisions
- Delete unapproved comments
- Remove spam comments
- Delete expired transients
- Optimize database tables
- Click "Run all selected optimizations"
Schedule Automatic Optimization
- Settings > Auto-clean
- Enable weekly optimization
- Save settings
Manual Database Optimization:
- phpMyAdmin
- DreamHost Panel > Goodies > phpMyAdmin
- Select your database
- Check all tables
- "With Selected" dropdown > "Optimize table"
Best Practices:
- Limit post revisions (add to wp-config.php:
define('WP_POST_REVISIONS', 3);) - Delete unused plugins and themes
- Clean up spam comments regularly
Step 7: Reduce Plugin Bloat
Each plugin adds code and database queries—use only essential plugins.
Plugin Audit Process
List All Plugins
- Plugins > Installed Plugins
- Review each plugin
Ask for Each:
- Is this still needed?
- Does theme have built-in alternative?
- Is there a lighter alternative?
- Can I achieve this with code snippet?
Deactivate Unused
- Deactivate plugins not essential
- Test site functionality
- Delete (not just deactivate) truly unused plugins
Combine Functionality
- Replace 5 specialized plugins with 1 comprehensive
- Example: Replace separate SEO, sitemap, schema plugins with Rank Math
Essential Plugins Only
Recommended Maximum: 15-20 active plugins
Essential Categories:
- Security (1 plugin - Wordfence)
- SEO (1 plugin - Rank Math or Yoast)
- Caching (1 plugin - WP Super Cache)
- Image Optimization (1 plugin - ShortPixel)
- Backup (1 plugin - UpdraftPlus)
- Contact Form (1 plugin - Contact Form 7)
- Page Builder (if needed - Elementor)
Avoid:
- Plugins doing one simple thing (use code snippet)
- Abandoned plugins (not updated 2+ years)
- Poorly rated plugins
- Plugins from unknown developers
Step 8: Choose Fast Theme
Theme choice dramatically affects speed.
Fast WordPress Themes
Free Themes:
- GeneratePress: Lightweight, fast, customizable
- Astra: Popular, speed-optimized, flexible
- Kadence: Modern, fast, feature-rich
- Neve: Lightweight, Elementor-ready
Premium Themes:
- GeneratePress Premium: $59/year, worth it
- Astra Pro: Fast with premium features
- Schema: Built for speed and SEO
Theme Speed Testing
Before Choosing:
- Install theme on test site
- Run Google PageSpeed Insights
- Check GTmetrix score
- Compare load times
- Choose fastest that meets design needs
Avoid:**
- Themes with built-in page builders (bloated)
- Demo sites with 50+ features you won't use
- Themes from unknown developers
- Themes not updated regularly
Step 9: Implement Advanced Optimizations
Enable GZIP Compression
What It Does: Compresses files before sending, reducing transfer size by 70%.
DreamHost Usually Enables by Default
Verify GZIP:
- Visit: https://checkgzipcompression.com
- Enter your URL
- Should show "Enabled"
Manual Enable (if needed):
Add to .htaccess:
<IfModule mod_deflate.c>
AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css text/javascript application/javascript
</IfModule>
Enable Browser Caching
Add to .htaccess:
## EXPIRES CACHING ##
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg "access plus 1 year"
ExpiresByType image/jpeg "access plus 1 year"
ExpiresByType image/gif "access plus 1 year"
ExpiresByType image/png "access plus 1 year"
ExpiresByType image/svg+xml "access plus 1 year"
ExpiresByType text/css "access plus 1 month"
ExpiresByType application/pdf "access plus 1 month"
ExpiresByType application/javascript "access plus 1 month"
ExpiresByType application/x-javascript "access plus 1 month"
ExpiresByType application/x-shockwave-flash "access plus 1 month"
ExpiresByType image/x-icon "access plus 1 year"
ExpiresDefault "access plus 2 days"
</IfModule>
