About SSL Performance Monitor

Monitors SSL/TLS handshake performance, connection times, and throughput metrics. Tracks performance degradation over time and identifies bottlenecks.

How to Use

1Enter your domain name and optional port
2Click "Measure Performance" to test connection
3Review DNS, TCP, and TLS handshake metrics

Use Cases

•Baseline performance measurement for your servers
•Detect performance regressions after changes
•Capacity planning and infrastructure optimization

Frequently Asked Questions

The monitor tracks DNS resolution time, TCP connection time, TLS handshake time, total connection time, and the negotiated TLS version. Each metric is color-coded for quick assessment.

For production servers, monitor regularly to establish baselines. Check performance after any infrastructure changes, and periodically to detect gradual degradation.

Common causes include slow DNS resolution, network latency, server load, weak cipher suites, and TLS version negotiation. Use the Handshake Debug tool for detailed analysis.

Tips & Best Practices

•Set up continuous performance monitoring for critical TLS endpoints
•Configure performance alerts for degraded TLS performance
•Track performance trends over time to identify degradation
•Use performance data to capacity plan and optimize infrastructure
