Use Case: Optimizing a Daily Word Game (Letter Boxed) Site with LiteSpeed Cache

#1
Hi everyone,

I wanted to share a small but interesting use case of running a daily word puzzle site (similar to Letter Boxed) on LiteSpeed and how I optimized it for performance and consistency.
Project Overview

The site publishes a new puzzle daily, with:

  • Mostly static content (letters + UI)
  • Some dynamic elements (user interactions, hints, tracking attempts)
  • Traffic spikes during specific hours (morning & evening)

LiteSpeed Setup

Here’s what worked well for me:

1. Full Page Cache

  • Enabled LSCache for anonymous users
  • Set moderate TTL (since content updates daily)

2. Cache Purge Strategy

  • Automatic purge scheduled when a new puzzle is published
  • Ensures users always see the latest puzzle without manual clearing

3. Object & Browser Cache

  • Reduced repeat requests for returning users
  • Helpful for frequent daily players

4. Compression

  • Enabled Brotli + GZIP (tested different levels for best balance)

5. Image Optimization

  • Used WebP for puzzle UI assets
  • Reduced initial load time significantly

Results

  • Faster initial page load during traffic spikes
  • Reduced server load compared to previous Apache setup
  • Consistent performance even with repeated visits

Challenges Faced

  • Aggressive CSS/JS minification broke some UI interactions (had to exclude specific files)
  • Cache conflicts when testing dynamic hints (solved using vary rules / exclusions)
  • Needed fine-tuning of TTL to match daily content updates

Questions for the Community

  • What’s the best approach for handling semi-dynamic content like hints or user progress?
  • Has anyone implemented separate cache versions for different user states (guest vs returning)?
  • Any recommendations for further optimizing small but high-frequency traffic apps like this?

There is nothing special with your specification. If you want real speed keep the cache always warmed or use LiteCache Rush. If you want Speed Illusion optimize.
