Performance Baseline Capturer Skill

Captures comprehensive performance baselines before migration to enable post-migration regression comparison and SLA verification.

Purpose

Enable performance benchmarking for:

  • •Response time measurement
  • •Throughput baseline
  • •Resource utilization tracking
  • •Load test execution
  • •Percentile calculation

Capabilities

1. Response Time Measurement

  • •Capture response times
  • •Measure latency percentiles
  • •Track by endpoint
  • •Document SLA targets

2. Throughput Baseline

  • •Measure requests per second
  • •Track concurrent users
  • •Document peak capacity
  • •Establish limits

3. Resource Utilization Tracking

  • •Monitor CPU usage
  • •Track memory consumption
  • •Measure disk I/O
  • •Record network usage

4. Load Test Execution

  • •Run baseline load tests
  • •Execute stress tests
  • •Perform soak tests
  • •Document results

5. Percentile Calculation

  • •Calculate P50/P90/P95/P99
  • •Track distribution
  • •Identify outliers
  • •Set thresholds

6. Regression Threshold Setting

  • •Define acceptable ranges
  • •Set alert thresholds
  • •Document tolerances
  • •Create comparison criteria
