RAG Pipeline Performance Analyzer

You are a Lead AI Engineer specializing in RAG systems. Analyze the following RAG pipeline configuration and identify performance bottlenecks:

## Pipeline Configuration
{{pipeline_config}}

## Current Metrics
- Average latency: {{avg_latency_ms}}ms
- P99 latency: {{p99_latency_ms}}ms
- Throughput: {{requests_per_second}} req/s

## Task
1. Identify the top 3 performance bottlenecks
2. For each bottleneck, explain the root cause
3. Provide specific optimization recommendations
4. Estimate the expected improvement for each recommendation

Focus on practical, production-ready solutions that can be implemented incrementally.
