How to measure and reduce Time to First Byte
Server and Hosting Improvements
Picking the right hosting provider and fine-tuning your server settings can significantly reduce TTFB (Time to First Byte).
Choose the Right Hosting Provider
When evaluating hosting options, focus on these key factors:
- Server Location: Place servers close to your target users to minimize latency.
- Infrastructure: Opt for SSD storage and up-to-date server software for faster performance.
- Resource Allocation: Dedicated resources often outperform shared hosting in terms of reliability and speed.
Look for providers that include CDN integration, server-side caching, and optimized configurations with regular performance monitoring to ensure a responsive experience.
Once your hosting is set, further enhance speed by enabling server caching.
Enable Server Caching
Server-side caching speeds up processing by storing pre-generated versions of your pages. Consider these caching methods:
- Page Caching: Save complete HTML outputs for faster delivery.
- Object Caching: Cache database query results to reduce repeated processing.
- Opcode Caching: Store precompiled PHP code for quicker execution.
- Browser Cache Headers: Configure headers to help browsers store static resources locally.
Beyond caching, optimizing your database can help eliminate backend delays.
Improve Database Performance
A well-optimized database ensures smoother operations and complements both hosting and caching efforts.
Database Setup:
- Turn on query caching.
- Optimize table structures for better efficiency.
- Use proper indexing to speed up lookups.
- Schedule regular maintenance to keep things running smoothly.
Query Optimization:
- Simplify JOIN operations to avoid unnecessary complexity.
- Write streamlined search queries.
- Remove redundant database calls to reduce load.
- Implement connection pooling to manage multiple requests efficiently.
These steps work together to create a faster, more reliable server environment.
Using CDNs Effectively
CDNs (Content Delivery Networks) deliver content from servers closer to your users, cutting down on latency and improving Time to First Byte (TTFB). Once you’ve optimized your server, a CDN adds an extra layer of performance improvement. Here’s how to make the most of it.
How CDNs Help with TTFB
CDNs work by distributing content across multiple servers worldwide, ensuring users get data from the nearest one. Here’s what they bring to the table:
- Lower server load: Your origin server handles fewer direct requests.
- Better reliability: Redundant servers ensure uptime even during high traffic.
- Stronger security: Built-in DDoS protection and SSL/TLS support keep your site safe.
- Global access: Content is delivered from local edge servers, no matter where your audience is.
"After OneNine took over a client’s website portfolio and implemented AWS CloudFront CDN, the site’s speed improved dramatically – with performance gains of over 700% and load times dropping to around one second." [1]
Choosing the Right CDN
When picking a CDN provider, focus on these factors:
Network Coverage
- Number and location of edge servers.
- Geographic reach that matches your audience.
- Network capacity to handle traffic spikes.
Performance Features
- Smart routing for faster delivery.
- File compression to minimize transfer size.
- Advanced caching options.
- Access to real-time performance data.
Security and Support
- Strong DDoS protection.
- SSL/TLS certificate management for secure connections.
- 24/7 technical support to resolve issues quickly.
- High uptime guarantees.
Setting Up Your CDN
Once you’ve selected a CDN, fine-tune it for the best results by focusing on these areas:
- Cache Settings: Configure cache durations for different content types, set cache invalidation rules, and enable text compression.
- Origin Shield: Add an extra caching layer to ease the load on your origin server and improve routing efficiency.
- Security Configuration: Ensure HTTPS is consistently applied across your site.
Keep an eye on your CDN’s performance and tweak settings based on traffic and usage trends. If managing a CDN seems overwhelming, consider working with experts like OneNine to handle the setup and ensure top-notch performance.

Reduce File Sizes and Requests
Once your server and CDN settings are optimized, the next step to improve TTFB is cutting down file sizes and requests.
Minimize HTTP Requests
Use browser developer tools to audit and reduce unnecessary HTTP requests. Here are some strategies:
- Combine Images and Icons: Use image sprites or icon fonts to replace multiple small image files with a single, consolidated file.
- Merge and Minify Files: Consolidate CSS and JavaScript files, then minify them to remove unnecessary characters.
- Remove Unused Scripts: Identify and eliminate third-party scripts that aren’t adding value.
Reducing the number of requests is just the beginning – file size optimization is equally important.
Compress Website Files
Shrinking file sizes helps speed up data transfer without sacrificing functionality. Here’s how:
- Optimize Images: Convert images to WebP format, use responsive images with
srcset, enable lazy loading, and compress them effectively. - Compress Text-Based Files: Enable GZIP or Brotli compression for HTML, CSS, JavaScript, JSON, and fonts.
- Minify Code: Remove comments, unnecessary formatting, and unused code. Shorten variable names to further reduce file size.
These steps ensure your site loads faster while maintaining its features.
Defer Non-Essential Content
Speed up the perception of your site’s loading time by delaying non-critical content:
- Inline Critical CSS: Keep essential styles inline and defer loading of non-essential JavaScript.
- Progressive Loading: Load key content first, then enhance the experience with techniques like skeleton screens or infinite scrolling.
Every kilobyte matters. Use tools like Google’s PageSpeed Insights to monitor performance and identify areas for improvement. Automate your build processes to ensure consistent optimizations over time.
Browser Cache and DNS Setup
Using browser caching and optimizing DNS settings can help reduce TTFB (Time to First Byte) by storing assets locally and speeding up domain resolution.
Set Browser Cache Rules
Browser caching saves assets on users’ devices, cutting down on server requests. Use Cache-Control headers to set appropriate expiration times:
| Content Type | Recommended Cache Duration | Update Frequency |
|---|---|---|
| Images/Icons | 1 year | Rarely changes |
| CSS/JavaScript | 6 months | Version controlled |
| HTML | 1 hour or no cache | Frequently updated |
| Dynamic Content | No cache | Real-time updates |
For Apache servers, include the following .htaccess directives:
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpeg "access plus 1 year"
ExpiresByType text/css "access plus 6 months"
ExpiresByType text/html "access plus 1 hour"
</IfModule>
Once caching is configured, focus on DNS settings for further speed improvements.
Speed Up DNS Lookup
Improving DNS lookup times can also reduce TTFB. Choose reliable DNS providers like Cloudflare, Google DNS (8.8.8.8), or Amazon Route 53. Additionally, enable DNS prefetching to resolve domain names in advance:
<link rel="dns-prefetch" href="//fonts.googleapis.com">
<link rel="dns-prefetch" href="//analytics.google.com">
These steps, combined with caching, significantly improve page load times.
Add DNSSEC Protection
DNSSEC enhances security while maintaining speed. To implement it:
- Work with your domain registrar to enable DNSSEC signing.
- Confirm the trust chain between your registrar and DNS provider.
- Use tools like DNSViz to monitor and validate DNSSEC performance.
For a hassle-free experience, services like OneNine can handle DNS optimization and security monitoring, ensuring your website runs efficiently and securely.
