How to send a large amount of data faster ?

Try moving some data to see how much is being moved

var n = 4, chk=5*1024;
var tdata=new Uint8Array(chk);
var i;
for(i=0;i<1024;i++){
  tdata[i]=0x30;
  tdata[i+1024]=0x31;
  tdata[i+1024*2]=0x32;
  tdata[i+1024*3]=0x33;
  tdata[i+1024*4]=0x34;
}//next i

function onPageRequest(req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  var t=getTime();
  res.on('drain',function() {
  print("n=",n,"t:",(getTime()-t).toFixed(3),"sec");
  if (n===0){ res.end();
   print("n=",n,"t:",(getTime()-t).toFixed(3),"sec");
  }else {  
   res.write(E.toString(tdata));  
    n--;
   }//end else
  });//end opr
 }//end function
