website speed FAQ
Basics of speed testing
What is a website speed test?
A page load time test measures how fast a page loads and what slows it down. It records time to first byte and Core Web Vitals. It is not a bandwidth check.
What are Core Web Vitals?
LCP is 2.5 seconds or less, INP is 200 milliseconds or less, and CLS is 0.1 or less, so you can optimize your page load time test results effectively. This is a test. Measure first, change one thing, and measure again to verify improvements.
Why does speed differ by region?
The website speed differs by region because the agent measures from your PC and connection only, so it cannot test other regions. Repeat tests. Compare the middle value of three runs to see the outcome.
Is this a load test?
No, a website speed test is a few ordinary page loads of your own site, so you should never send many requests to a site you do not own. It is not a load test. Test your own website or one you are responsible for.
Using Decade Web
Does Decade Web run on Windows?
Yes, Decade Web runs tools and shows results, and it supports 13 languages without an account to help you fix website loading speed today. The setup program is about 34 MB for Windows and is ready to use.
How does the agent help with speed?
The agent helps with speed by using http_get to fetch your page and read response headers, and it uses grep to find the heaviest files. Yes, it does. It uses edit_file to propose changes and Shell to save results.
Are the results always right?
No, a test from one PC is a single lab measurement and differs from real visits, so the reader checks every result and diff before accepting changes. Speed matters. A faster number does not guarantee more traffic or sales.
What are the approval modes?
Approval modes are three settings that control how the agent executes actions, so you can choose Auto-run, Ask first, or Plan only for your workflow. Yes, this mode is useful. Plans survive restarts without running commands immediately, allowing you to review changes before execution begins.
Models, privacy and download
Do my files leave the PC?
Chats and working folders stay on the PC, and secrets in tool output are redacted before they reach the model for safe processing. Yes. No telemetry is sent to any external server during local processing.
How do I verify the download?
One of the best ways to test website speed is to measure first and change one thing, so you can see the real impact on performance. Check the file. Verify the download using certutil and compare the hash.
Is webdecade.com the official Decade Web website?
Yes, webdecade.com is the official Decade Web website for the Windows app, and the download button gives the setup program (~34 MB) for Windows 10/11. Press download. Pressing download records time, IP address, browser user agent and referral source.
