Performance Optimization
Comprehensive strategies and tools for optimizing LLM performance, reducing latency, improving throughput, and maximizing cost efficiency.
Overview
Performance Optimization in LLMOps focuses on maximizing the efficiency and effectiveness of LLM operations while minimizing costs and resource usage. This includes optimizing model performance, reducing latency, improving throughput, and implementing intelligent caching strategies.
Key Performance Metrics
Core Metrics to Track
- Latency - Response time (p50, p95, p99)
- Throughput - Requests per second
- Token Efficiency - Tokens per query
- Cost per Query - Total cost including compute and API calls
- Error Rate - Failed requests percentage
- Cache Hit Rate - Percentage of cached responses
