Stress-test your processor using a multi-threaded Web Worker for 10 seconds.
This test will heavily utilize one of your CPU cores to calculate prime numbers. Your browser may warn you about high usage.
This benchmark runs an intensive mathematical algorithm (a prime number sieve) inside a background thread called a Web Worker.
Because it runs in the background, your browser interface stays perfectly smooth while your CPU core is pushed to 100% utilization. The final score is based on the total number of primes calculated within the 10-second limit.
