iPad 2 iOS 8.3 Performance #88

Closed phet-steele closed 8 years ago

phet-steele commented 9 years ago

With an iPad 2, iOS 8.3 (our device labeled Tycho), on the Lab screen I was getting a constant 10 fps in 1.0.0-dev.4. Things enabled:

  1. Two masses, both swinging around 30 degrees
  2. Default lengths and masses
  3. No friction
  4. Velocity checked
  5. Acceleration checked
  6. Energy graph expanded
  7. Gravity maxed at 25.00

Compared to Chrome 43 on Win 8.1: ~35 fps

Slightly better on iOS 7.1, ~14 fps

Made some performance optimizations. Reassign to @phet-steele for verification.

I'll investigate this performance as part of https://github.com/phetsims/pendulum-lab/issues/18
