What is the Computer Speed Test?
Is your computer fast, or just feels slow? This benchmark runs eight short workloads directly in your browser — integer maths, floating-point (a Mandelbrot render), sorting numbers and objects, text processing, memory bandwidth, JSON conversion and SHA-256 hashing — times each one, and combines them into a single performance score where higher means faster.
The score is designed for comparing your own devices, browsers and settings: a phone against a laptop, Chrome against Firefox, battery-saver against high-performance mode, or before and after you close background apps. Your last ten runs are saved in your browser so you can watch the trend. It is a browser benchmark, not a full hardware review, so treat it as a practical everyday-performance indicator.

Questions people ask
What does the score mean?
It combines the speed of eight tests. It has no fixed scale, so use it to compare your own devices and settings.
Why do my results vary?
Background tasks, temperature and power mode change speed. Run several times.
Is this a CPU benchmark?
It measures browser performance that depends on the CPU, memory and browser engine — a good everyday indicator, not a synthetic hardware test.
Will it slow down my computer?
It uses the processor heavily for a few seconds and then stops.
Are results uploaded?
No. History is stored only in your browser.
