First Contentful Paint (FCP) – When the very first text or image shows.
Largest Contentful Paint (LCP) – Measures important content loading speed.
Time to First Byte (TTFB) – Check server response speed.
Here’s a complete and practical breakdown of the process of how to run a website speed test:
1. Select the Appropriate Speed Testing Tool
Some tools are completely free, and there are paid tools that help to test website speed instantly. Well-
known ones are:
All the above-mentioned tools provide valuable insights into Core Web Vitals, load time, and server
response time.
2. Test from Different Available Places
The main step in how to run a website speed test is all about testing the website from different
locations. A website may load instantly in local places but show issues for worldwide users. Tools such
as GTmetrix enable selecting multiple test locations.
3. Utilize Both Desktop & Mobile-Based Tests
With the help of mobile-first indexing, testing the site on both mobile and desktop is very important.
Generally, most of the mobile users experience very slow speeds, so improving speeds is a must.
4. Pay Proper Attention to Main Metrics
At the time of learning about how to run a website speed test, try to focus more on all these key
metrics:

4. Cumulative Layout Shift (CLS) – Guarantee visual stability.
Fully Loaded Time – When every script, image, and content finishes the loading process.
Only Testing Once: Performance changes with growing traffic and time.
Ignoring Mobile Results: Most of the site traffic at present comes from mobile users.
Not Checking Server Response: A lot of people focus only on design, but a slow,
dedicated server can be the main reason.
Forgetting About Hosting Quality: A badly configured GPU hosting plan can disable all
advanced optimizations.
5. Run Tests Many Times
A single test won’t give a clear picture of the speed. As you know, server performance can vary, so
always run as many tests as possible at different times of the day.
6. Check Server Performance
The GPU server, or dedicated server, is the one that plays a very important role in the case of website
performance. If TTFB is constantly high, it may take some time to scale your hosting.
Basic Mistakes to Prevent While Running Speed Tests
Even if you are experienced in running a website speed test, it’s very common to make mistakes that
can result in misleading outcomes:

5. A GPU server manages high-traffic sites and AI-powered tasks with full comfort.
A dedicated server makes sure that there is no resource allocation.
GPU hosting improves performance for all those websites that need complex data
processing.
A streaming server improves real-time video and audio delivery.
Improving Outcomes After Performing a Speed Test
Running the speed test is not the full task; it’s just half the job. Here is a complete breakdown of how
to act on the outcomes:
1. Improve Images & Videos
Huge media files just slow down websites. Compress every image and use a CDN for streaming.
2. Allowing Browser Caching
Caching stores assets locally for quicker user visits again and again.
3. JavaScript, Minify CSS & HTML
Smaller sizes of files refer to quicker load times.
4. Utilize a Content Delivery Network (CDN)
Allocate content universally so that every user gets access to data from the closest location.
5. Upgrade Your Hosting Environment
One of the noteworthy improvements always comes from improved hosting:
Service providers like Infinitive Host provide all of these options, ranging from enterprise-level GPU
dedicated server to flexible cloud solutions.
