Time-Consuming instead of Slow:
"Slow" conveys the idea that there is a problem that needs to be looked into. The results shown in this view are not necessarily slow...they just happen to be the ones consuming the most time.
Requests instead of Pages:
With the shift to SPA's and AJAX, it more often that the Web App is serving all sorts of Requests rather than just Pages (like in the earlier days of Web Forms).
Thank you for the feedback. I agree that "Slow Pages" conveys that a threshold has been hit to be added to the slow pages "list".
I think even "Slowest Pages" would better describe this dashboard data as we are ordering it based on time so the slowest pages could still be fast (i.e. under 1 second).
