What this tool analyzes

  • Response times: Average, minimum, and maximum so you see slow endpoints.
  • Error rates: HTTP status codes and failure patterns.
  • Headers: Request and response headers for caching and compression.
  • Payload size: Request and response body sizes.
  • Connection issues: Timeouts, failures, and retry behavior.

Common performance issues

  • Slow responses: Endpoints that take too long to respond.
  • High error rates: Endpoints that fail often.
  • Large payloads: Requests or responses that send more data than needed.
  • Missing headers: No caching or compression headers.
  • Connection problems: Network or timeout issues.

Ways to improve

  • Use caching (ETags, Cache-Control) where it fits.
  • Enable compression (gzip or brotli) for large responses.
  • Shrink payloads by returning only required fields.
  • Batch requests and use pagination.
  • Serve static assets from a CDN.
  • Tune database queries that back your APIs.
