Why is Javascript ReadLine() performance 100000% slower than Jscript?

I have tried using both methods - aqFile and the above. The performance is atrocious.

Here is our Jscript code - 
var pathToTXT = ProjectSuite.Variables.FCINSTALLPATH+"\\Setup\\__createdb.log";
var logMethod = "Warning";
if(!aqFile.Exists(pathToTXT))
{
Log.Error(pathToTXT+" does not exist.");
return;
}
else
var openTXT = aqFile.OpenTextFile(pathToTXT, aqFile.faReadWrite, aqFile.ctANSI); //open createdb text file

var lineToBeRead;
var compare;
var secureRole;
var counter = 0;
openTXT.Cursor = 0;
while(!openTXT.IsEndOfFile())
{
lineToBeRead = openTXT.ReadLine();
compare = lineToBeRead.search("ORA-");
if(compare > -1)
{
secureRole = lineToBeRead.search("28405");
if(secureRole == -1) //This will ignore thie specific errror
{
if(logMethod == "Errors" || logMethod == "errors")
Log.Error("Line " + counter +": " + lineToBeRead);
if(logMethod == "Warnings" || logMethod == "warnings")
Log.Warning("Line " + counter +": " + lineToBeRead);
}
else
{
Log.Message("Line " + counter +": " + lineToBeRead);
}
}
counter++;
}
openTXT.Close();
