Request performance using Html.BeginForm versus jQuery AJAX

Is there any gain in performance when using jQuery to perform ajax requests in relation to the post using Html.BeginForm?

@using (Html.BeginForm("Create", "Teste")
    {
        @Html.AntiForgeryToken()
        @Html.ValidationSummary(true, "", new { @class = "text-danger" })
        <div class="form-group">
           @Html.LabelFor(m => m.Nome, new { @class = "col-md-2 control-label" })
        <div class="col-md-10">
        @Html.TextBoxFor(m => m.Nome, new { @class = "form-control" })
        <span class="help-block">@Html.ValidationMessageFor(model => model.Nome, "", new { @class = "text-danger" })</span>
   }
   <div class="form-group">
      <div class="col-md-offset-2 col-md-10">
         <input type="submit" class="btn btn-default" value="Enviar" />
      </div>
   </div>

If it is better to do via ajax request, do you have any sample code where you deal with ValidationSummary and ValidationMessageFor?
