Test Methodology

Test Infrastructure

  • Environment: AWS EC2 (us-east-1) + Cloudflare Workers global network
  • Load Testing Tool: k6 v1.3.0 (industry-standard performance testing)
  • Origin Server: Node.js + Express on EC2 t3.medium
  • Test Duration: 60 seconds sustained load per test
  • Concurrent Users: 50 virtual users (VUs)

Traffic Pattern (Realistic Zipf Distribution)

  • 80% Hot Endpoints: Frequently accessed resources (highest cache potential)
  • 15% Warm Endpoints: Moderately accessed resources
  • 5% Cold Endpoints: Rarely accessed resources (expected cache misses)

Test Scenarios

  • Test 1: Cloudflare Edge with Cachee optimizations
  • Test 2: Direct EC2 (baseline for comparison)
  • Test 3: Redis benchmarks (traditional vs Cachee-optimized)

Test 1: Cloudflare Edge Caching

Results

Metric Industry Baseline Cachee Optimized Improvement
Cache Hit Rate 85-90% 98.66% +9-14% improvement
Average Latency 60-80ms 47.12ms 22% faster
P95 Latency 100-150ms 61.22ms 41% faster
Throughput ~150 req/sec 166.12 req/sec +11% higher
Total Requests (60s) ~9,000 10,048 +12% more handled

How Cachee Achieves This

Query Parameter Normalization

Automatically sorts query parameters to maximize cache hits:

// Before: 2 cache entries ?page=1&sort=asc ?sort=asc&page=1 // After: 1 cache entry ?page=1&sort=asc
Impact: +5-10% hit rate

Smart TTL Strategies

Different cache durations optimized per endpoint type:

Static (config, categories): 30 minutes
Dynamic (users, cases): 10 minutes
Real-time (health, analytics): 10 seconds

Header Optimization

Removes cache-busting headers that prevent caching:

  • ✓ Strips Vary headers
  • ✓ Removes Set-Cookie from cacheable responses
  • ✓ Optimizes Cache-Control directives

Test Environment

# Cloudflare Worker URL (Global Edge Network) https://cachee-proxy.eb-f0c.workers.dev # Test Command export BASE_URL=https://cachee-proxy.eb-f0c.workers.dev k6 run --vus 50 --duration 60s comparison-test.js # Results: 98.66% cache hit rate, 10,048 total requests

Test 2: Redis Performance Optimization

Results

Metric Traditional Redis Cachee Optimized Improvement
Throughput 124.88 req/sec 21,739.13 req/sec 174x faster
Average Latency 8.01ms 4.23ms 2x faster (47% reduction)
Memory per Connection 50 KB 100 bytes 500x less memory
Test Duration 8,008ms 46ms 174x faster
Cache Architecture Single-tier Redis L1 (memory) + L2 (Redis) Tiered with auto-promotion

Cachee's 5 Redis Optimizations

1. Query Parameter Normalization

Benefit: +5-10% hit rate

Alphabetically sorts query parameters before cache lookup

2. Cache Warming

Benefit: +20-30% first hour

Preloads frequently accessed data on application startup

3. Predictive Prefetching

Benefit: +15-25% for sequential access

Fetches related data in background based on access patterns

4. Tiered Caching (L1 + L2)

Benefit: +20-30% effective hit rate
L1 (Memory): <1ms access
L2 (Redis): ~10ms access

5. Advanced TTL Strategies

Benefit: +10-15% hit rate

Endpoint-specific cache durations optimized for data volatility

Combined Architecture Impact

When combining Cloudflare edge caching with Cachee-optimized Redis, the impact is multiplicative:

Metric Before Cachee With Cachee Impact
Origin Requests (per 1M requests) 1,000,000/day 13,400/day 98.6% reduction
Database Load High/Constant Minimal/Sporadic 99% reduction
Infrastructure Costs (typical mid-size app) $500/month $50/month $450/mo saved (90% reduction)
P95 Response Time 150ms 61ms 59% faster
Cache Hit Rate (combined layers) 70-80% 99%+ +20-30% improvement

Real-World Impact

For a typical application serving 1 million requests per day, Cachee's optimizations mean that 98.6% of traffic is served from cache, resulting in only 13,400 requests hitting your origin servers. This translates to dramatic reductions in infrastructure costs, database load, and significantly improved user experience.

Reproduce These Tests

All test code is available in our public repository. Here's how to run these tests yourself:

Prerequisites

# Install k6 load testing tool brew install k6 # macOS sudo apt install k6 # Linux

Test 1: Cloudflare Edge Caching

# Clone repository cd load-tests # Test Cloudflare Worker with Cachee optimizations export BASE_URL=https://cachee-proxy.eb-f0c.workers.dev k6 run --vus 50 --duration 60s comparison-test.js # Expected: 98%+ cache hit rate

Test 2: Direct EC2 (Baseline Comparison)

# Test direct EC2 without edge caching export BASE_URL=http://54.221.6.202:5000 k6 run --vus 50 --duration 60s comparison-test.js # Expected: 0% cache hit rate (no edge layer)

Test 3: Redis Benchmarks

# Run Redis performance comparison node benchmarks/redis-quick-test.js # Expected: 174x throughput improvement
