Slow-query impact calculator

Compute the total exec time burned by one slow signature — and what optimizing it would save. Pair with EXPLAIN to justify the work.

Time burned now

8500.0 days

Annual exec time at current p99

Time burned after

1200.0 days

Annual exec time at target p99

Time saved

7300.0 days

86% reduction · ~21900 engineer-days of CPU

Model: time saved = (calls/sec × Δlatency) over the active window. Real-world savings are usually larger because slow queries also burn locks, connections, and tail latency on unrelated traffic — not modeled here.

Free, no signup, no email gate. Computations run client-side — your numbers never leave the browser.
