example I find that the script is faster

var liText = '', liList = $('#myid li'), listForRemove = [];

$(liList).each(function () {

  var text = $(this).text();

  if (liText.indexOf('|'+ text + '|') == -1)
    liText += '|'+ text + '|';
  else
    listForRemove.push($(this));

})?;

$(listForRemove).each(function () { $(this).remove(); });
