Regex 如何加快谷歌应用程序脚本执行时间

这个脚本处理来自GMAIL线程的3个CSV文件，执行时间很快，直到我添加了搜索正文的regex部分

tmp = truncatedContent.match(/Date Tripped:\s*([:\w\s]+)\r?\n/);
tmp = truncatedContent.match(/Business Date:\s([\w\s]+\(\w+\))/);

添加此部分后，脚本将成功完成，但现在需要大约17秒才能完成，而不是之前的4秒

我想这里有一个非常有效的方法，寻求指导：

function SLSalesImportFromGmail() {
  var ss = SpreadsheetApp.getActive(); // Get the spreadsheet file once

  //gets first(latest) message with set label
  var threads = GmailApp.getUserLabelByName('South Loop').getThreads(0,1);
  if (threads && threads.length > 0) {
    var message = threads[0].getMessages()[0];
    // Get the first email message of a threads
    var content = message.getPlainBody();
    var tmp,
    truncatedContent = content.match(/^([^\r\n]+\r?\n){5}/)[0];
    // Get the plain text body of the email message
    // You may also use getRawContent() for parsing HTML
    // Implement Parsing rules using regular expressions
    if (truncatedContent) {

      tmp = truncatedContent.match(/Date Tripped:\s*([:\w\s]+)\r?\n/);
      var tripped = (tmp && tmp[1]) ? tmp[1].trim() : 'N/A';

      tmp = truncatedContent.match(/Business Date:\s([\w\s]+\(\w+\))/);
      var businessdate = (tmp && tmp[1]) ? tmp[1].trim() : 'N/A';
    // Get all of the attachments and loop through them.
    var attachments = message.getAttachments(); 
    for (var i = 0; i < attachments.length; i++) {
      var attachment = attachments[i];
      var title = attachment.getName();

      // Is the attachment a CSV file
      attachment.setContentTypeFromExtension();
      var table = Utilities.parseCsv(attachment.getDataAsString());
      if (attachment.getContentType() === "text/csv") {
        switch (title) { // Update the specified sheets
          case "Sales.csv":
            /**
            * Clears the sheet of values & formatting and inserts the new table 
            * using the Apps Script built-in CSV parser.
            * @param {string} sheetName - The name of the sheet to update
            * @returns {undefined}
            */
            ss.getSheetByName("South Loop Sales").getRange("A:M").clear();
            ss.getSheetByName("South Loop Sales").getRange(1, 1, table.length, table[0].length).setValues(table);
            ss.getSheetByName("South Loop Sales").appendRow(['Last Sync:', tripped]);
            ss.getSheetByName("South Loop Sales").appendRow(['POS Date:', businessdate]);
            break;
          case "Labor.csv":
            ss.getSheetByName("South Loop Labor").getRange("A:M").clear();
            ss.getSheetByName("South Loop Labor").getRange(1, 1, table.length, table[0].length).setValues(table);
            break;
          case "ServerPerformance.csv":
            ss.getSheetByName("South Loop Servers").getRange("A:M").clear();
            ss.getSheetByName("South Loop Servers").getRange(1, 1, table.length, table[0].length).setValues(table);            
            break;
        }
      }      
    }
    if( message.getSubject().indexOf('END OF DAY') !== -1) {
    SLlogTodaysSales();
    SLlogTodaysServers();
    }
    if( message.getSubject().indexOf('END OF WEEK') !== -1) {
    SLlogTodaysSales();
    SLlogTodaysServers();
    SLlogWeeksLabor();
    }
    }
    //marks the Gmail message as read, unstars it and deletes it using Gmail API (Filter sets a star)
  message.markRead();
  message.unstar();
  Gmail.Users.Messages.remove("me", message.getId()); // Added
  }
}

function SLlogTodaysSales() {
  var todaysSales = SpreadsheetApp.getActive().getRange('South Loop Sales Log!SLSalesImport');
  var logSheet = todaysSales.getSheet();
  logSheet.appendRow(
    todaysSales.getValues()
    .reduce(function(a, b) { return a.concat(b); }) // flatten the 2D array to 1D
  );
}
function SLlogWeeksLabor() {
  var ss=SpreadsheetApp.getActive();
  var sh=ss.getSheetByName('South Loop Labor Log');
  var rg=sh.getRange('SLLaborImport');
  var vA=rg.getValues();
  sh.getRange(sh.getLastRow()+1,1,vA.length,vA[0].length).setValues(vA);
}
function SLlogTodaysServers() {
  var ss=SpreadsheetApp.getActive();
  var sh=ss.getSheetByName('South Loop Server Log');
  var rg=sh.getRange('SLServerReport');
  var vA=rg.getValues();
  sh.getRange(sh.getLastRow()+1,1,vA.length,vA[0].length).setValues(vA);
}

从.appendRow切换到.getRange/.setValue。 更改：
