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.
