animation ios webkit cpu直接占滿

<template lang="pug">
    svg.ui_wave(xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" viewBox="0 24 150 28" preserveAspectRatio="none")

        g.ui_wave_parallax
            use(xlink:href="#gentle-wave" x="50" y="0" fill="rgba(255, 255, 255, 0.1)")
            use(xlink:href="#gentle-wave" x="50" y="3" fill="rgba(255, 255, 255, 0.1)")

move-forever動畫里如果不注釋transform cpu占的特別多。 請問怎么優(yōu)化?
如圖所示
