Benchmark: drawImage vs draw path

HTML Preparation code:

<canvas id="canvas" width="1024" height="1024"></canvas>
<canvas id="backCanvas" width="1024" height="1024"></canvas>

Script Preparation code:

const canvas = document.getElementById('canvas')
const backCanvas = document.createElement('canvas')
backCanvas.width = canvas.width
backCanvas.height = canvas.height

const ctx = canvas.getContext('2d')
const backCtx = backCanvas.getContext('2d')

const path = new Path2D();
for(const i = 0; i < canvas.width; i+=5) {
  path.moveTo(i, 0)
  path.lineTo(i, w)
}
for(const i = 0; i < canvas.height; i+=5) {
  path.moveTo(0, i)
  path.lineTo(h, i)
}

backCtx.stroke(path)

Tests:

Sroke path
ctx.stroke(path)
draw saved canvas
ctx.drawImage(backCanvas, 0, 0)
