What is TTFB by Chrome version
TTFB by Chrome version shows the Time to First Byte (TTFB) performance across different versions of Google Chrome. While TTFB is mostly tied to network and server conditions, this view helps surface browser-specific patterns — including quirks, bugs, or compatibility issues that affect initial loading time.
Only versions that sent traffic in the selected timeframe are shown. Both mobile and desktop Chrome are included.
Why this matters: Certain Chrome releases may change how requests are initiated, how early hints are handled, or how connection reuse is prioritized — all of which can influence perceived TTFB.
Healthy TTFB by Chrome version sample
Should you worry
A healthy TTFB by Chrome version view is stable across major versions. A bit of natural variance is fine, especially between mobile and desktop traffic, but no red zones should appear unless tied to connection quality — not browser version.
Unhealthy TTFB by Chrome version sample
If newer versions of Chrome are consistently slower at reaching your server:
It might be due to changes in preconnect or DNS handling.
HTTP/3 or protocol negotiation differences could be impacting timing.
Third-party scripts injected early might delay network initiation.
Chrome may be interacting poorly with your server’s TLS setup or cache strategy.
Older versions might also show worse TTFB if they lack modern protocol support — but that’s only a concern if those users are still a large percentage of your traffic.
Resolving unhealthy TTFB by Chrome version
Go-to action plan to resolve an unhealthy TTFB by Chrome version:
Ask Uxi to analyze your TTFB by Chrome version values and suggest improvements.
Filter by version and compare with distance, country, and connection lenses to isolate root causes.
Simulate TTFB of the suspected lens to see if fixing it will resolve the TTFB by Chrome version. If yes, this is where the resolution focus should be.
Use an automated optimization tool like Navigation AI to improve your TTFB by Chrome version values.
Once you’ve improved TTFB, set an alert to be the first to know if it starts worsening again.
