Magento Performance Audit · Complete Edition
The store is slow. Someone wants a bigger server, someone else installs a "speed optimization" extension, a third person flushes the cache three times. Two weeks and a few invoices later, the store is still slow and nobody can say why, because nobody measured anything before touching it.
Magento Performance Audit is the method that breaks that loop. You measure first, find the bottleneck with evidence and fix what costs the most first. The way a senior engineer does it, step by step, with the command for every check.
What you will be able to do:
• Build a baseline in percentiles (p90, p99) and prove any improvement with a number, not a hunch.
• Find the queries that burn the most database seconds per day and decide which one to fix first.
• Prove the cache (Varnish, Redis/Valkey) is on, varies correctly and is not being flushed for no reason.
• Find the code that weighs on the MISS, the admin, cron and the queues.
• Pass Core Web Vitals on field data (p75), not just on Lighthouse.
• Size PHP-FPM and load-test the peak before the campaign.
• Tell customers from bots and stop scrapers at the edge (CDN/WAF).
• Set up the monitoring routine that keeps the store from getting slow again.
What is in the Complete Edition:
• Vol. 1 · The Origin (PDF + EPUB): method, baseline, database, cache and code.
• Vol. 2 · From the Edge to the Browser (PDF + EPUB): frontend, infrastructure, bots and observability.
• The complete edition in a single file (PDF + EPUB, about 700 pages).
• The 201-check checklist as a spreadsheet in English (Excel and CSV): how to check, pass criteria, weight and a score per area.
• A report template to hand to the client or the team, with the matrix that sorts out what to fix first.
This is not a list of tips. Every check tells you how to check it, what counts as a pass and how much it weighs. The cases come from real stores, anonymized, with the before and after measured. There are 74 charts and diagrams, concept boxes for newcomers and a glossary.
