KendoUI组合框加载数据的速度更快

Question

我可以用数据库集成（PostgresSQL）在kendoUI combobox中显示数据，但我的组合框执行速度比我预期的慢1-2秒，当我单击下拉箭头时。任何人都可以帮我解决当我点击组合框的下拉列表时如何加载数据的速度更快吗？

<div class="col-sm-5 col-xs-10"> 
        <div class="col-sm-2 text-center col-xs-3"><h4>MPID</h4></div> 
        <div class="col-sm-5 col-xs-9"> 
         @(Html.Kendo().ComboBox() 
         .Name("cmbBrokers") 
          .DataTextField("MPID") 
          .DataValueField("MPID") 
          .Placeholder("--") 
          .HtmlAttributes(new { style = "width:300px" }) 
          .Events(e => { e.Change("onClientSelect"); }) 
          .Filter(FilterType.StartsWith) 
          .DataSource(source => 
          { 
           source.Read(read => 
           { 
            read.Action("GetBrokers", "BrokerMapping"); 
           }).ServerFiltering(false); 
          }) 
           .HeaderTemplate("<div class=\"dropdown-header \">" + 
        "<span>MPID</span>" + 
        "<span>Name</span>" + 
        "<span>NSCCID</span>" + 
       "</div>") 
     .FooterTemplate("Total <strong>#: instance.dataSource.total() #</strong> items found") 
     .Template("<div class=\"dropdown\"><span> #:data.MPID# </span><span>#: data.CompanyName #</span>" + "<span>#: data.NSCCID #</span></div>") 
         ) 
        </div> 

**Here is my javascript** 
<script> 
function searchData(searchText) {  
    var grid = $("#brokersGrid").data("kendoGrid"); 
    var dataSource = grid.dataSource; 

    dataSource.filter({ 
     logic: "or", 
     filters: [{ 
      "field": "MPID", 
      "operator": "startswith", 
      "value": searchText 
     }, 
      { 
       field: "CompanyName", 
       operator: "startswith", 
       value: searchText 
      }, 
      { 
       field: "NSCCID", 
       operator: "startswith", 
       value: searchText 
      }] 
    }); 
} 
function onClientSelect(e) { 
    var searchText = this.value(); 
    document.getElementById("txtSearch").value = ""; 
    searchData(searchText); 
} 
function brokersGridDataBound(e) { 
    var combo = $("#cmbBrokers").data("kendoComboBox");  
    combo.dataSource.read(); 
}
