如何加速谷歌应用程序脚本api调用xml for循环和sub for循环键值存储

Question

请有人可以审查并建议探索优化和加速的途径。我没有想法。这是一个从谷歌电子表格应用程序脚本调用的功能，现在有200多个工作，有点慢。

有关更快构造的建议，而不是＆＃34; for＆＃34;环？或者其他聪明的优化想法。它是通过键值存储解析任务的子例程吗？也许有一种更聪明的方法可以做到这一点？

有兴趣学习更好的方法。

非常感谢你能花一点时间来帮助

function updateTracker() {
  var output = [];

  // fetch and parse doc
  var document = xmlFetch('https://api.blahblah');

  //locate child set
  var jobset = document.getRootElement().getChild("Jobs").getChildren();

  var WFMcallstatus = document.getRootElement().getChild("Status").getValue();
  if (WFMcallstatus != "OK") {  
    return "Call Failed"
