neurolink generate "Memory test" --dryRun &
ps -o rss -p $! | tail -1  # Baseline memory

neurolink generate "Memory test" --evaluationDomain analytics --enable-evaluation --enable-analytics --dryRun &
ps -o rss -p $! | tail -1  # Domain feature memory

CLI Startup Optimization

Fast Startup Strategies

Use Specific Commands

# Faster - direct command
neurolink generate "prompt" --dryRun

# Slower - with help lookup
neurolink help generate

Optimize Environment

# Pre-configure providers to avoid runtime detection
export GOOGLE_AI_API_KEY="your-key"
export OPENAI_API_KEY="your-key"

# Use specific provider to skip auto-detection
neurolink generate "prompt" --provider google-ai --dryRun

Configuration Caching

# Initialize configuration once
neurolink config init

# Configuration validation (cached after first run)
neurolink config validate

Startup Performance Monitoring

# Profile CLI startup with detailed timing
NODE_OPTIONS="--prof" neurolink generate "test" --dryRun
node --prof-process isolate-*.log > startup-profile.txt

# Monitor system calls during startup
strace -c neurolink --version 2>&1 | grep -E "(calls|syscall)"

Domain Configuration Performance

Efficient Domain Usage

Choose Appropriate Domain

# Use specific domain for better performance
neurolink generate "healthcare query" --evaluationDomain healthcare  # Optimized
neurolink generate "healthcare query" --evaluationDomain analytics   # Less optimized

Selective Feature Enablement

# Enable only needed features
neurolink generate "prompt" --evaluationDomain healthcare --enable-evaluation  # Evaluation only
neurolink generate "prompt" --evaluationDomain healthcare --enable-analytics   # Analytics only
neurolink generate "prompt" --evaluationDomain healthcare --enable-evaluation --enable-analytics  # Both (higher overhead)

Configuration Defaults

# Set defaults to avoid runtime overhead
neurolink config init
# Configure default domain and features during setup

Domain-Specific Optimizations

# System memory monitoring
top -p $(pgrep -f neurolink)

Generation Speed Optimization

Speed Optimization Strategies

Provider Selection for Speed

# Fast providers for quick responses
neurolink generate "prompt" --provider google-ai --max-tokens 500

# Quality vs speed tradeoff
neurolink generate "prompt" --provider anthropic --max-tokens 1000  # Higher quality, slower
neurolink generate "prompt" --provider google-ai --max-tokens 800   # Faster response

Optimal Token Limits

# Right-size token limits for your use case
neurolink generate "brief summary" --max-tokens 200      # Fast
neurolink generate "detailed analysis" --max-tokens 1500  # Comprehensive

Format Selection Impact

# Text format (fastest)
neurolink generate "prompt" --format text

# JSON format (slight overhead for parsing)
neurolink generate "prompt" --format json

# Table format (most processing overhead)
neurolink generate "prompt" --format table

Generation Performance Monitoring

# Time different configurations
hyperfine 'neurolink generate "test" --dryRun' \
          'neurolink generate "test" --evaluationDomain healthcare --dryRun' \
          'neurolink generate "test" --evaluationDomain analytics --enable-analytics --dryRun'

# Profile generation performance
time neurolink generate "performance test prompt" \
  --evaluationDomain analytics \
  --enable-evaluation \
  --enable-analytics \
  --format json \
  --max-tokens 1000

Streaming Performance

Streaming Optimization

Efficient Streaming Setup

# Optimized streaming command
neurolink stream "streaming prompt" \
  --evaluationDomain analytics \
  --enable-evaluation \
  --provider google-ai

Streaming vs Generation Trade-offs

# Use streaming for real-time feedback
neurolink stream "long analysis" --evaluationDomain healthcare

# Use generation for batch processing
neurolink generate "batch analysis" --evaluationDomain healthcare --format json

Streaming Performance Monitoring

# Monitor streaming latency
time neurolink stream "test prompt" --dryRun

# Monitor streaming throughput
neurolink stream "long content generation" --dryRun | wc -c

Streaming Best Practices

# Optimal streaming configuration
neurolink stream "complex analysis requiring real-time feedback" \
  --evaluationDomain analytics \
  --enable-evaluation \
  --provider google-ai \
  --max-tokens 1500

Provider Selection Strategy

Performance-Based Provider Selection

Speed-Optimized Providers

# Fastest response times (typically)
neurolink generate "prompt" --provider google-ai

# Good balance of speed and quality
neurolink generate "prompt" --provider openai

# Higher quality, potentially slower
neurolink generate "prompt" --provider anthropic

Domain-Specific Provider Optimization

# Healthcare domain - high accuracy priority
neurolink generate "medical query" --provider anthropic --evaluationDomain healthcare

# Analytics domain - speed and structured output
neurolink generate "data analysis" --provider google-ai --evaluationDomain analytics

# Finance domain - precision and compliance
neurolink generate "financial analysis" --provider openai --evaluationDomain finance

Provider Performance Testing

# Compare providers for your use case
for provider in google-ai openai anthropic; do
  echo "Testing $provider:"
  time neurolink generate "test prompt" --provider $provider --evaluationDomain analytics --dryRun
done

Context Data Optimization

Efficient Context Structures

Optimized Context Design

# Efficient - flat structure
neurolink generate "prompt" \
  --context '{"userId":"123","department":"analytics","priority":"high"}' \
  --evaluationDomain analytics

# Less efficient - deeply nested
neurolink generate "prompt" \
  --context '{"user":{"profile":{"details":{"id":"123","dept":{"name":"analytics"}}}}}' \
  --evaluationDomain analytics

Context Size Guidelines

# Small context (<1KB) - optimal performance
neurolink generate "prompt" --context '{"key":"value","count":5}'

# Medium context (1-5KB) - good performance
neurolink generate "prompt" --context '{"data":["item1","item2","item3"],"meta":{"version":"1.0"}}'

# Large context (>5KB) - potential performance impact
# Consider breaking into smaller requests or summarizing

Context Caching Strategies

# Reuse context across related queries
CONTEXT='{"organizationId":"acme","department":"analytics","quarter":"Q3"}'

neurolink generate "query1" --context "$CONTEXT" --evaluationDomain analytics
neurolink generate "query2" --context "$CONTEXT" --evaluationDomain analytics
