视图渲染时间过长

Question

我必须用大量数据填充部分视图。我首先在服务器上进行 ajax 调用：

$.ajax({
    url: '/Monitoring/_Thresholds?workspaceID=' + workspaceID,
    type: "POST",
    data: new FormData(form),
    cache: false,
    contentType: false,
    processData: false,
}).success(function (result) {
    resultsDiv.innerHTML = result;
}).error(function (response) {
    resultsDiv.innerHTML = response.responseText;
});

但是由于数据量太大，执行此操作花费的时间太长，我得到：

HTTP Error 502.3 - Bad Gateway

The specified CGI application encountered an error and the server terminated the process.

Most likely causes:

The CGI application did not return a valid set of HTTP errors. A server acting as a proxy or gateway was unable to process the request due to an error in a parent gateway.

Things you can try:

Use DebugDiag to troubleshoot the CGI application. Determine if a proxy or gateway is responsible for this error.

BL 的东西需要 2-3 秒，但渲染视图要多得多。

有什么办法可以解决吗？

Answer 1

rc1-final渲染大视图中有known performance issue

为 rc2 准备好修复。我想尽量把视图变小。
