    Your code enhance the performance of 'ws' aobut five times.

    in the 'ws' codes:

        var mask = [];
        for (var ix = 0; ix < 4; ix++){
          var rnd = Math.floor( Math.random() * 255 );
          mask[ix] = rnd;
          //masked += strChr(rnd);
        var masked = new Uint32Array(1+((msg.length+3)>>2));
        var m8 = new Uint8Array(masked.buffer, 0, (4 + msg.length));
        var m = masked[0];
        for (var i=1;i<masked.length;i++) {
        // E.mapInPlace could be even faster here


    connected? err= null info= {
      "ip": "",
      "netmask": "",
      "gw": "",
      "mac": "30:ae:a4:03:96:a8"

    ERROR: Out of Memory!
    ERROR: Ctrl-C while processing interval - removing it.
    Execution Interrupted during event processing.
    at line 1 col 461
    in function "send" called from line 2 col 23
    in function called from system

    What strange is that after 60 packets are transfered, the program throws " out of memory " error, every time.

    AND , when the server receives the second packet, it crashed every time.

    Server is listening on port 5004
    a client connected
    isTalking : false
    <Buffer 81 fe>
    received data: 1,230
    <Buffer 35 38>
          throw er; // Unhandled 'error' event
    Error: invalid opcode: 5

    The first two bytes of the first packet is correct, and that of the second packet is wrong. The first tow bytes of the second(and every frame/packet) should be , but they are now.

    The error is throwed by the codes in Receiver.js of ws module on nodejs

    if ((buf[0] & 0x30) !== 0x00) {
          this.error(new Error('RSV2 and RSV3 must be clear'), 1002);

    I'll try to find the problem.
