# Memory vs Latency

Quick Reference: Step 4: Caching | Throughput vs Latency

# Quick Reference

Memory: Cache more data for faster access

Latency: Reduce memory usage for lower latency

Trade-off: More memory = faster access but higher cost

# Clear Definition

Memory vs Latency trade-off: More memory (caching) reduces latency but increases cost. Less memory reduces cost but increases latency.

💡 Key Insight: Cache frequently accessed data. Balance memory cost with latency requirements.

# Core Concepts

# Caching Strategies

• Cache Hot Data: Frequently accessed
• Eviction Policies: LRU, LFU
• Memory Limits: Set appropriate limits

# Best Practices

1. Cache Strategically: Cache hot data only
2. Monitor Hit Rate: Track cache effectiveness
3. Balance: Balance memory cost with latency

# Quick Reference Summary

Memory: More memory = faster access but higher cost.

Latency: Less memory = lower cost but higher latency.

Key: Cache strategically, balance cost and performance.
