Slow-query signal (normalized)
Part of the Schema & indexes check · fix arrives as a guide
What it is
The database statistics show queries with a slow-execution signal, normalised across their parameter values.
Why it matters
These are the statements consuming the most time, and normalising by shape shows which pattern is responsible rather than which individual execution was unlucky. A slow shape run frequently costs more than a slow one run rarely.
How to fix it
Take the top statements by total time and run an execution plan on each. Sequential scans on large tables and sorts spilling to disk account for most of what turns up.
