Optimize NetSuite restlet to avoid timeout error

Question

I'm writing a restlet that will return all Bill, Credit Card, and Journal transactions within a NetSuite account (see code below). My issue is that given the volume of data (100k+ transaction records), I'm getting a timeout error. Is there any way for me to optimize my code to avoid this timeout error? Is there a way for me to pass the restlet parameters around the PageRanges and just make multiple calls?

/**
 *@NApiVersion 2.x
 *@NScriptType Restlet
 */
 define(['N/error', 'N/search'],
 function(error, search) {
     function doValidation(args, argNames, methodName) {
         for (var i = 0; i < args.length; i++)
             if (!args[i] && args[i] !== 0)
                 throw error.create({
                     name: 'MISSING_REQ_ARG',
                     message: 'Missing a required argument: [' + argNames[i] + '] for method: ' + methodName
                 });
     }
     function _get(context) {
         doValidation('GET');
        
         var mySearch = search.create({
            type: search.Type.TRANSACTION,
            columns: ['account', 'recordtype','trandate', 'tranid', 'memo', 'amount', 'department', 'entity' ],
            filters: [['recordtype', 'is', 'vendorbill'], 'or', ['recordtype', 'is', 'creditcardcharge'],'or', ['recordtype', 'is', 'journalentry']]
        });
        results = []
        var myPagedData = mySearch.runPaged({
            pageSize: 1000
        })

        myPagedData.pageRanges.forEach(function(pageRange){
            var myPage = myPagedData.fetch({index: pageRange.index})
            results.push(myPage.data)
        })
        return results
         }  
         
     return {
         get: _get,
     };
 });

You can refresh the restLet for time exceed error as it has 5 minute(300 seconds) time limit only. you can use N/runtime moduleto get its governance limit and N/cache module to store the already done data. check the remaining governance and curren t time in loop. and break the loop and call again restLet after storing already done data using cache module. Pass remaining data as a parameter while calling.

 var script_startdate = new Date(); // this will be in starting on script 
function
script_Start_time = script_startdate.getTime(); 
for(var i=0;i<i+2;i++){   // here i used infinity loop, you can use yours
var script_workdate = new Date();
var script_workTime = script_workdate.getTime();
remainingTime= script_workTime - script_Start_time;
var remainingContentIndex=content.indexOf(content[i]);
var remainingUsage = runtime.getCurrentScript().getRemainingUsage();
if ((remainingTime> 240000) ||(remainingUsage<80))break;
}

if ((substraction > 240000) ||(remainingUsage<80))
   {
      var myCacheRecId = cache.getCache({
           name: 'temporaryCacheRecId',
           scope: cache.Scope.PUBLIC
           });
        myCacheRecId.put({
              key: 'myvar',
              value: "already completed data""
              });
     var slice_index=remainingContentIndex+1;
     var remainingContent=content.slice(slice_index);
     var content=content.toString(remainingContent);
              redirect.redirect({
                scriptId: 'customscript_scriptid,
                deploymentId: 'customdeploy_deployid',
                  parameters: {
                       content: content
                        }
                      });
                  log.debug("called restlet", "called restlet");
    
           };
