Tool Context

Performance Monitor sits in Core Monitoring

Performance Monitor helps profile response speed, first-byte latency, and delivery overhead when a site feels slow and you need a fast, honest server-side read.

Core Monitoring

DNS, SSL, performance, API, and related health checks.

Core Monitoring

DNS, SSL, performance, API, and related health checks.

Deep Validation

Security, content, synthetic journeys and sitemap quality.

Operations and Reporting

Workspace-first alerts, incidents, and stakeholder reporting workflows.

Suggested workflow

Launch Access

Guests can try the tools, while signed-in workspaces keep the durable state

Current session: Guest

Guest access

Guests can run live response profiles with tighter caps and no saved workspace history.

Logged-in workspace

Logged-in workspaces keep higher launch limits and a cleaner path into the rest of SynapWatch.

This page stays honest during launch: guests can run real server-side response profiles, while account access gives you more headroom and continuity.

Live Response Profile

Profile the real server response path

Run a real server-side profile for first byte, total response time, redirects, and cache behavior. This stays intentionally narrow so the output remains trustworthy.

What You Get

Measured in this run

  • First-byte latency and total response time
  • Redirect hops and final destination URL
  • Cache, content, and delivery headers

Launch access

  • Guests can run real one-off response profiles
  • Free accounts keep higher daily room and workspace continuity
  • No fake browser-vitals data is shown here

Honesty note

This is a server-side response profiler, not a browser Lighthouse run. SynapWatch only shows measurements it can actually prove from this environment.

What a live profile gives you

  • Status code and final URL after redirects
  • First-byte timing versus end-to-end response time
  • Cache-Control, Content-Type, and Server-Timing clues

Delivery details

Run a profile to capture read size, content type, redirect count, and cache headers.

Interpretation

Once a profile exists, SynapWatch will summarize what the measured timing suggests.
