Your First Analysis

Your first analysis

Run one

Go to Super Speedy, Performance Analysis and start an analysis. It profiles your key pages: home, shop, archives, search, checkout, wp-admin lists and editors.

It takes seconds to a couple of minutes depending on the site. Each page gets a warm-up request and three measured samples, and the medians are what you see.

From the command line, wp sspa run --type=spot.

Read the Overview

The site score, out of 100, with the five insights that matter most, each naming the component responsible and what to do about it.

The Health box confirms the two helpers are installed and tells you if a page couldn't be measured because a cache served it.

Autoloaded options names the options that no profiled page read, and the size they cost on every request, with copy-and-paste SQL. Bear in mind it can only see pages the analysis touched: an option read solely by a page nothing profiled will be listed as unused.

Then go where the number points

The score tells you whether there's a problem. These tell you what it is:

• One page stands out: Per-Page-Analysis
• You want to know which plugin is genuinely responsible rather than which one ran the queries: Plugin-Impact-Analysis
• The shop feels slow at the till: Checkout-and-Order-Flow-Analysis
• Saving a product takes forever: Update-and-Save-Analysis
• You want logged-in visitors served from cache: Cache-Optimisation-Analysis

The seven tabs

Overview, Pages, Plugins, History, Tools, Traffic and Share.

Pages drills into a per-plugin breakdown, the slowest queries with their callers, and the HTTP calls. Plugins shows per-plugin SQL time, query counts, rows fetched and slowest query across the analysis, plus the measured impact column that Plugin-Impact-Analysis fills. History tracks the score, findings and median generation time across runs, so you can see whether the site is getting slower as it grows. Tools is Server-Capabilities. Share is The-Community-Plugin-Database.

What the numbers mean

If page generation time is a new idea, read what it is and how to bring it down first. For the method behind the measurement, including the attribution trap every profiler has, see How-It-Measures.
