WEBSITE SPEED TEST

on all Devices based on Perceived

Performance using Artificial Intelligence

What is Perceived Performance ?

Perceived Performance is a measure of how fast user feels your website loading instead of how long it took to fully load your website.

Why Perceived Performance is Important ?

It's what matters. We are doing Web Performance Optimization with one thing in mind: users. We are not optimizing for a technical score or to reduce infrastructure costs; we are optimizing to increase user experience that leads to more conversion. Perceived Performance is what matters.

Perceived performance is the only performance we should take care of. The best measurements in standard metrics are worth nothing if the user only sees a blank page or a loading spinner. Make sure you get to show contents fast, load incrementally, and prioritise what’s important for your users. Performance is a user experience topic, after all.

How do you measure Perceived Performance ?

At Perfhack we measure perceived performance using PUIT (Perfhack User Impression Time). PUIT is the time taken by the browser to display the content so that user can start doing his primary activity like reading content, entering form input etc.. We calculate PUIT using Artificial Intelligence based on deep learning and other algorithms. Right now we are accurate more than 95% of the time and we are confident that we will reach 99.9 % accuracy very soon as we get more data.

WHY WE NEED TO DO SPEED TEST
ACROSS ALL DEVICES


Every website will have users from different devices not just from a single device type. Website speed on mobile & Tablet is as important as on Desktop & Laptop.

Processors,Graphics Cards,Ethernet Cards etc... varies depending upon device type which will drastically change website performance.
