Track TTFB, Latency & Response Times with Sub-Second Precision

Monitor Time To First Byte, total request time, and regional latency from 25+ locations. Set performance thresholds, track percentiles (P50/P95/P99), detect degradation trends, and get alerted before users complain about slowness.

Complete Performance Visibility

Beyond up/down -- know when your site is slow

TTFB Monitoring

Track Time To First Byte -- the first indicator of server performance. Catch slow database queries or overloaded servers.

Historical Trends

View response time over 1 hour, 24 hours, 7 days, 30 days, 90 days. Identify degradation patterns.

Performance Alerts

Set thresholds: 'Alert if response time > 2 seconds'. Get notified before users complain.

Percentile Metrics

Track P50, P95, P99 latency. Know if 1% of requests are slow or if everyone is affected.

Regional Comparison

Compare response times across regions. 'Fast in US, slow in Asia' -- now you know where to optimize.

Real-Time Tracking

See current response times live. Verify optimizations immediately after deployment.

Start Response Time Monitoring

Track performance in 3 steps

1

Set Performance Baseline

Define acceptable response times (e.g., <500ms excellent, 500-2000ms acceptable, >2000ms slow).

2

Configure Alerts

Get notified when: response time > threshold, sudden spikes occur, or performance degrades over time.

3

Track Trends

View detailed charts showing average, min, max latency. Compare pre-deployment vs post-deployment performance.

Who Uses Response Time Monitoring?

Speed matters for everyone

E-commerce

Every 100ms delay costs 1% of sales. Track checkout page performance and optimize for conversions.

SaaS Applications

Users expect <200ms response times. Monitor API endpoints and ensure snappy user experience.

DevOps Teams

Verify deployments don't slow down your site. Compare before/after performance metrics.

SEO Managers

Page speed affects rankings. Track Core Web Vitals and ensure Google sees your site as fast.

Response Time Monitoring FAQ

Common questions about performance tracking

What's a good response time?

<200ms = excellent, 200-500ms = good, 500-1000ms = acceptable, 1-2s = slow, >2s = very slow. Depends on application -- APIs should be faster than content pages.

What's the difference between response time and page load time?

Response time = server response only (TTFB). Page load time = full page render including CSS, JS, images. We track response time; use PageSpeed monitoring for full load time.

Can I set different thresholds for different pages?

Yes! Each monitor has separate thresholds. APIs can have 200ms limit, while admin pages can have 1000ms limit.

How often do you measure response time?

Every check interval (5 min Free, 1 min Pro). Every successful check records response time -- thousands of data points per month.

What causes slow response times?

Overloaded servers, slow database queries, unoptimized code, network congestion, or CDN issues. Our regional data helps pinpoint the cause.

Can I compare response times before and after deployments?

Yes! View historical charts and compare any time periods. Perfect for A/B testing optimization changes.

Do you alert on temporary spikes or sustained slowness?

Both! Configure: 'Alert if >2s for 5 consecutive checks' (sustained) or 'Alert immediately if >5s' (spike). Your choice.
