WebKit 27 JavaScriptCore Probe

This page checks how WebKit 27's JavaScript engine performs under four repeatable, CPU-intensive workloads. It does not use WebGL, draw graphics, or run game logic.

What will be tested?

• Floating-point math: 10 million arithmetic updates and conditional checks using ordinary JavaScript numbers.
• Object property access: 4 million reads and writes across 1,024 reusable vector-like objects.
• Mixed method calls: 2 million calls alternating between two object types, testing how the engine optimizes object-oriented code.
• CANNON physics: 288 moving spheres are simulated inside a fixed enclosure for 20 measured steps after a 10-step warm-up. The test separately measures broadphase collision search, exact collision detection, and constraint solving.

The first three tests run three timed passes and report the fastest result. The physics test reports average and maximum time per step. Lower times are better; higher millions of iterations per second are better. Keep this page visible until the benchmark finishes.
