#typo3performance

A quick website keeps visitors engaged and encourages them to explore more. It also improves visibility in search results. With TYPO3 Performance Optimization, your site can deliver the speed and efficiency users expect.

Checking Site Speed First

Use tools like Google PageSpeed Insights, GTmetrix, WebPageTest

Check metrics such as:

Largest Contentful Paint (LCP) – how long the main content appears

Total Blocking Time (TBT) – delays from JavaScript

Cumulative Layout Shift (CLS) – page shifting during load

First Input Delay (FID) – how fast the site responds to user input

Measure both desktop and mobile, because mobile often loads slower

Picking the Right Hosting

Shared hosting can be slow under heavy traffic

Better choices: TYPO3-specific hosting, VPS or dedicated server, cloud hosting

Keep your server close to your main audience for faster delivery

Making Images Lighter

Resize to the exact size needed

Use modern formats (WebP, AVIF)

Apply lazy loading so off-screen images load later

Compress files to shrink size without losing much quality

Using TYPO3 Cache Features

TYPO3 has built-in caching, make sure it is active

Options include static file caching or external systems like Redis or Varnish

Choose proper storage (file system or database)

Clear cache when needed via backend, CLI, or toolbar

Handling CSS and JavaScript

Merge files to reduce requests

Minify to strip out unnecessary characters

Load scripts later in the page so the main content appears faster

Compressing with Gzip or Brotli

Enable compression to shrink file transfer size

Gzip works everywhere, Brotli can be faster where supported

Test to confirm compression is active

Adding a Content Delivery Network

A CDN serves files from servers closer to the visitor

Works well for images, CSS, and JS

Set up DNS and configure TYPO3 to send assets through the CDN

Test before and after to see improvements

Cleaning Database and Queries

Remove unused data, logs, or revisions

Use TYPO3 commands to clean safely

Optimize tables to keep them healthy

Avoid slow search queries, use exact matches or full text search

Turning on PHP OPcache

Speeds up PHP by storing compiled code in memory

Enable in php.ini, adjust settings, restart server

Check with phpinfo that it is working

Reduces CPU use and speeds up script handling

Ongoing Testing and Monitoring

Test after each change

Keep monitoring regularly, since speed can change with updates or traffic growth

Gradual improvements lead to a smoother visitor experience
