Performance Mode — Speed Up Your API

Is your faynoSync instance handling thousands of update checks per minute? Worried about database load? Meet Performance Mode — your API's new best friend for handling high traffic efficiently!

What is Performance Mode? 🤔​

Performance Mode is a smart caching system that:

  • 🚀 Reduces response times
  • 📉 Lowers database load
  • 💾 Optimizes resource usage

It works by caching frequently requested data in Redis, making your API responses lightning-fast!

How It Works 🛠️​

The Magic Behind the Scenes​

  1. Request Arrives 📥

    • API checks if Performance Mode is enabled (PERFORMANCE_MODE=true)
    • Looks for cached data in Redis

  2. Cache Check 🔍

    • If data exists in cache → returns it immediately
    • If not → queries the database

  3. Cache Update 💾

    • New data is stored in Redis
    • Ready for next request

What Gets Cached?​

Currently, Performance Mode is implemented for the checkVersion endpoint, which is one of the most frequently called endpoints in the system.

Why Do We Need It? 🎯​

1. Database Load Reduction​

  • 📊 Fewer queries to MongoDB
  • 💪 Less strain on your database
  • 🎯 Better resource utilization

2. Faster Response Times​

  • ⚡ Cached responses are returned instantly
  • 🏎️ No need to wait for database queries
  • 🎮 Perfect for high-traffic scenarios

3. Resource Optimization​

  • 🌱 Lower CPU usage
  • 💧 Reduced memory consumption
  • 📈 Better scalability

How to Enable It? 🔌​

Just add this to your .env file:

PERFORMANCE_MODE=true

That's it! Your API will automatically start using Redis for caching.

Testing Performance 🧪​

Want to see the difference? Try this test script:

start_time=$(date +%s); 
for i in {1..1000}; do 
  response=$(curl -s -w "Connect Time: %{time_connect}s, Start Transfer Time: %{time_starttransfer}s, Total Time: %{time_total}s\n" -o /dev/stdout --location 'http://localhost:9000/checkVersion?app_name=myapp&version=0.0.3&channel=nightly&platform=null&arch=null'); 
  echo "$response"; 
done; 
end_time=$(date +%s); 
total_time=$((end_time - start_time)); 
echo "Total execution time: $total_time seconds"

Compare the results with and without Performance Mode enabled!

Important Notes 📝​

  1. Cache Invalidation 🔄

    • Cache is automatically cleared when you publish a new version
    • New data is cached on the next request
    • Ensures users always get the latest information

  2. Current Implementation 🎯

    • Only implemented for checkVersion endpoint
    • Perfect for high-frequency update checks
    • More endpoints might be added in the future

  3. When to Use ⚡

    • High-traffic environments
    • Systems with frequent update checks
    • Scenarios where response time is critical

Best Practices 💡​

  1. Enable in Production 🚀

    • Always use Performance Mode in production
    • Especially if you expect high traffic

  2. Monitor Performance 📊

    • Keep an eye on response times
    • Watch Redis memory usage
    • Track database load

  3. Regular Updates 🔄

    • Cache is automatically managed
    • No manual intervention needed
    • Just focus on your app!
