Speed Lab: FAQ

What is the Speed Lab?

A small WordPress site on the same Hostinger server as this site (digitalpritam.in/lab/), with no plugins installed. We add one plugin at a time, measure it, and remove it.

Why a clean site?

So the only thing that changes between runs is the plugin. It removes ads, themes and other plugins from the results.

Where is the raw data?

Every Speed Lab page publishes its timed requests so you can check our medians. Data is free to reuse with a link (CC BY 4.0).

Is the lab public?

No. It is hidden from search engines and only used for tests. Results appear as pages on this site.
