Request Timeout & Latency Diagnostic
Compare a measured response time against your latency budget and find where to look.
Private by design. Every tool runs 100% in your browser — your code, text, and tokens never leave your device. Nothing is uploaded or stored.
Compares a measured response time against your latency budget and suggests where to look. It does not measure the network for you — use your APM or browser devtools for the raw number.
Slow: 1200 ms exceeds your 800 ms budget.
- Profile the slowest span.
- Consider caching or a CDN for static parts.
- Verify the client timeout is not firing early.
Frequently Asked Questions
What is a reasonable latency budget?
A common target is under 100ms for same-region API calls and under 300ms end-to-end for user-facing requests. Anything above your budget warrants a look at the slowest leg.
Where does latency usually hide?
DNS, TLS handshake, cold starts, and N+1 database queries are the usual culprits. Compare your measured time against the budget to see which leg dominates.
Does a timeout mean the server is down?
Not necessarily. A timeout can be a slow dependency, a stuck connection, or a misconfigured client timeout that is shorter than the real response time.
