What is TTFB by weekday
TTFB by weekday measures backend responsiveness for each day of the week, showing the Time to First Byte (TTFB). This is key for spotting infrastructure or routing slowdowns tied to specific weekday operations.
Healthy TTFB by weekday sample
Should you worry
In a healthy view, TTFB stays consistently low regardless of weekday, even when load increases during Monday restocks, mid-week campaigns, or weekend traffic spikes.
Unhealthy TTFB by weekday sample
If TTFB is slower on certain weekdays, it may point to batch jobs, database maintenance, or under-provisioned servers during predictable high-load periods.
Resolving unhealthy TTFB by weekday
Go-to action plan to resolve an unhealthy TTFB by weekday:
Ask Uxi to analyze your TTFB by weekday values and suggest improvements.
Use Filters to target slow regions, templates, or API endpoints on affected days.
Simulate TTFB of the suspected breakdown to see if fixing it will resolve the TTFB by weekday. If yes, this is where the resolution focus should be.
Use an automated optimization tool like Navigation AI to improve your TTFB by weekday values.
Once you’ve improved TTFB, set an alert to be the first to know if it starts worsening again.
