KendoUI組合框加載數據的速度更快

Question

我可以用數據庫集成（PostgresSQL）在kendoUI combobox中顯示數據，但我的組合框執行速度比我預期的慢1-2秒，當我單擊下拉箭頭時。任何人都可以幫我解決當我點擊組合框的下拉列表時如何加載數據的速度更快嗎？

<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(); 
}
