Performance practice

Find what makes it slow.

The slow job, pipeline or hot path your business waits on. We measure it, explain it, then fix it against the number: code, queries, I/O, concurrency or infrastructure.

  1. 01 / 03 Baseline

    Measure the whole run.

    We time the slow path end to end, including the parts that are not the database, and write the baseline down: the metric, how it is measured, and the variance across runs.

  2. 02 / 03 Findings

    Name what costs the most.

    Each finding is traced to code, a query or a setting, and ranked by the time or cost it recovers. If we find nothing worth fixing, the report says so.

  3. 03 / 03 Fix

    Fix it against the number.

    The fix is a second fixed-price SOW, measured against the baseline the diagnosis set, with a benchmark plan so the gain is proven rather than claimed.

One 41-minute run, span by span. The costliest span is marked, then each fix shortens the run.

What breaks

It got slow with volume.

A database health check tunes indexes. This is an application-level diagnosis across code, queries, I/O, concurrency and infrastructure, for the case where the database is only part of the answer. What we usually find:

  • An N+1 pattern that grew with the data.
  • A query plan that changed with volume, or an unindexed scan.
  • Work that runs in series when it could run in parallel.
  • Output written one row at a time.
  • A fix that was tried without a baseline, so nobody knows what it changed.

The time each fix recovers per run, against the 41-minute run traced above. The roadmap then orders them by effort.

How a diagnosis runs.

  1. 01 / 04 5 working days

    Assess

    The Performance Diagnosis: a measured baseline and an end-to-end trace of the slow path, including the parts that are not the database.

  2. 02 / 04 Report

    Plan

    Findings ranked by time or cost recovered, a roadmap ordered by effort, and a benchmark plan, so the fix is proven.

  3. 03 / 04 Fixed price

    Build

    The fix, as a second fixed-price SOW, measured against the baseline the diagnosis set.

  4. 04 / 04 Yours

    Hand over

    The fix, the benchmark and the baseline numbers move to your team, so the next change is measured the same way.

Most likely

A growth-linked database term: an unindexed scan, an N+1 pattern, or a query plan that changed with volume. Fixable, and the diagnosis quantifies how much of the baseline it is.

Measure this before you call anyone

  1. Write down the baseline: the metric, how you measure it, three runs, and the variance.
  2. Get one end-to-end trace or profile of a full run, not a single query.
  3. Find a way to run the path outside production with realistic data, even a subset.
  4. Re-run the previous fix attempt with the baseline measurement so you know what it changed.

Illustrative example, not a client's data.

Record

Proven on a 27-hour job.

Our principal, Rey Narvaez, delivered these results in regulated production before Aripone was formed.

  • 27h → 8h

    A regulated calculation job cut from 27 hours to 8 per run, so it can run three times as often.

  • 30%

    About 30% of the database load removed from a production platform.
