Slow server response
time to first byte (TTFB)
The page takes a long time before anything appears. It can be heavy code, no server-side cache or the account resources. This cannot be settled from the outside — it needs a look inside the site.
DoSieci Speed Check
Free WordPress and WooCommerce performance audit
Start with the speed test — the result appears straight away, no email needed. The full technical audit is free as well; you only pay for the fixes.
DoSieci Speed Check
External test vs. full technical audit
The free test and the paid audit answer different questions. The test says something is slow. The audit says why and exactly what to fix.
This test was run without access to the admin panel, database or server. It cannot see SQL queries, WP-Cron, Action Scheduler, PHP configuration, logs or how plugins behave internally. The full technical audit covers those.
The free external test sees:
- ✓PageSpeed mobile and desktop scores
- ✓Core Web Vitals from Google field data (when available)
- ✓HTTP headers, caching, compression and redirects
- ✓detected technology (WordPress, WooCommerce, Cloudflare, cache)
- ✓the top three problems and three areas to improve
The full technical audit additionally covers:
- ✓the database, wp_options and autoload
- ✓SQL queries, WP-Cron and Action Scheduler
- ✓plugins and the theme from the inside
- ✓PHP, OPcache and PHP-FPM
- ✓logs and the server environment, where available
- ✓fix priorities and an implementation quote
After the test
You have a result — what next
The result shows a symptom. Below are the most common signals and what follows from them. The direction comes from which part is slow, not from the score itself.
Heavy images and scripts
largest element (LCP), transfer size
The main element loads slowly because images are served at full resolution or the theme loads scripts the page never uses. This is usually work on the site, not the server.
No caching or compression
HTTP headers
Every visit builds the page from scratch and files travel uncompressed. This can normally be fixed by configuration, without rebuilding the site.
If the test does not finish or the page returns a 5xx error, that is not a performance issue but a failure — report it as a technical problem. Want us to look at the result? There is a button under the report that opens a short form: the report id and the tested address are attached automatically, you copy nothing. We will tell you what the measurement means and what the scope of work would be. We change nothing on your site before the scope is agreed.

DoSieci Speed Check
What the full technical audit covers
The test analyses publicly available parameters: PageSpeed scores, Core Web Vitals from Google field data, HTTP headers and detected technology. A full diagnosis of the database, WordPress and the server requires a technical audit.
- ✓WordPress and WooCommerce — configuration, theme, plugins
- ✓the database, wp_options and autoload
- ✓SQL queries and the heaviest operations
- ✓WP-Cron and Action Scheduler
- ✓PHP, OPcache and PHP-FPM
- ✓the caching layer (page, object, browser, CDN)
- ✓logs and the server environment, where we have access
- ✓a prioritised fix list and a rough implementation quote
Implementation scope — WordPress
- ✓page and object cache configuration
- ✓image optimization and next-gen formats
- ✓reducing and deferring CSS and JavaScript
- ✓tidying plugins and scheduled tasks
- ✓database cleanup and indexes
- ✓before/after measurements and key-page checks
We confirm the scope after the audit and before implementation begins.
Implementation scope — WooCommerce
- ✓everything from the WordPress scope
- ✓cart, checkout and account page
- ✓Action Scheduler, queues and order events
- ✓fragment cache and exclusions for dynamic pages
- ✓payment, shipping and third-party integrations
- ✓checking the purchase flow before and after changes
We confirm the scope after the audit and before implementation begins.

FAQ
Frequently asked questions
How is the free test different from the full audit?+
The test only sees what the site exposes publicly: PageSpeed scores, Core Web Vitals and headers. It cannot see SQL queries, WP-Cron, Action Scheduler, PHP configuration or how plugins behave internally — that is covered by the full technical audit, which is also free.
Do you guarantee a 100/100 score?+
No. Real speed and stability matter more than a synthetic score, and results depend on features, ads and third-party tools. We also do not promise a specific sales increase or search ranking.
How much does a performance fix cost?+
The audit is free. Implementing the fixes costs PLN 500 for a standard WordPress site and PLN 2,500 for a standard WooCommerce store. Large stores and code rebuilds are quoted individually after the audit.
Do I need to change hosting?+
Not always. The audit first determines whether the limit is in the site, its configuration or the server environment.
Does the test require an email?+
No. You see the basic result without providing any data. You only enter an email if you want to send the result for review and a quote.
