Benchmark: createElementNS vs cloneNode

Tests:

createElementNS
const list = [] let n = 1e5 while (--n) { const c = document.createElementNS('http://www.w3.org/2000/svg', 'circle') c.setAttribute('cx', 39) c.setAttribute('cy', 0) c.setAttribute('r', 20) list.push(c) }
cloneNode (shallow)
const list = [] let n = 1e5 - 1 const c = document.createElementNS('http://www.w3.org/2000/svg', 'circle') c.setAttribute('cx', 39) c.setAttribute('cy', 0) c.setAttribute('r', 20) list.push(c) while (--n) { list.push(c.cloneNode(false)) }
cloneNode (deep)
const list = [] let n = 1e5 - 1 const c = document.createElementNS('http://www.w3.org/2000/svg', 'circle') c.setAttribute('cx', 39) c.setAttribute('cy', 0) c.setAttribute('r', 20) list.push(c) while (--n) { list.push(c.cloneNode(true)) }
