jQueryUI:自动完成大数据是悬挂浏览器

我在我的项目中使用jQueryUI的autcomplete.我有一个自动完成文本,其中用户搜索的东西和相应的数据下拉.

使用小数据集,它工作正常.当数据集很大时会出现问题.我有几乎1L记录具有唯一值,我作为源附加autocomplete.

现在,一旦用户在文本栏中输入搜索字符串,浏览器就会因为autocompletejQueryUI 的处理而挂起原因.

我想知道如何优化它或使其更快,以便borwser不会挂起.这里的plunkr我创建的发挥.这就是我将源连接到自动完成的过程.

$("#tags").autocomplete({
      source: availableTags
});

而不显示所有50000条记录仅显示前10条.最小搜索字符长度从默认0增加到2

$(function () {
            var availableTags = [
              "ActionScript",
              "AppleScript",
              "Asp",
              "BASIC",

                availableTags.push('abc' + i);
            }
            $("#tags").autocomplete({

                source: function (request, response) {
                    var results = $.ui.autocomplete.filter(availableTags, request.term);

                    response(results.slice(0, 10));
                }
            });
