Animations performance in internet explorer 7

Question

I am maintaining a legacy code at work that runs on internet explorer 7, and I have performance issues on the old hardware.

Css animation being not supported in IE7, I've tried jquery animate but the results were horrible, I've tried to replace theme with Velocity.js, I've seen some minor performance gains but still not enough.

containerReference
  .delay(3000)
  .velocity({
    top: '25px'
  }, {
    'easing': 'linear',
    'duration': 1600
  })
;

Any idea how to improve performance?

Do you know about any tiny compiled framework that could help (sveltJS maybe)?
