我有一份大报告。SQL 只需要大约 60 秒的时间来运行，但 PDF 的实际呈现却是一直占用的时间。它有数百页。
请求超时的全局设置设置为 240 秒。
我正在覆盖此报告的全局设置并将值设置为任意高（3600 秒）。实际上，这份报告的完成时间不会超过 15 分钟。
无论我将超时设置多高，此页面都会在超时之前产生时间限制错误。
SQL 可能需要 24 秒到 4 分钟才能完成，具体取决于选择的区域数量。
即使我覆盖了超时，页面在完成查询后大约 170 秒（只有一个数据点）会生成错误。因此，有时甚至在全局超时之前整整一分钟都会发生这种情况。
cfdocument 渲染 PDF 所需的时间是否有限制？
有没有办法增加超时？
这可能与最大输出缓冲区大小等其他东西有关吗？
这是我用来测试请求超时的自定义函数：
<cffunction name="getCurrentRequestTimeout" output="false" access="private" returntype="numeric">
<cfset var rcMonitor = createObject("java", "coldfusion.runtime.RequestMonitor") />
<cfreturn rcMonitor.getRequestTimeout() />
</cffunction>
我将它放在几个位置以确定超时设置是否正确。在所有情况下，它都返回 3600 秒。
编辑，这是另一个线索：
此报告交叉引用来自其他 8 个查询（已在控制器中运行）的数据，它在视图中进行交叉引用。大约一年前，我们通过为我们交叉引用的查询创建哈希值大大加快了速度（将运行时间从 1 小时缩短到 10 分钟）。完成了一项任务，以完全删除我们从报告中散列的 4 个查询。一旦我将那些 BuildHashTable 函数调用从视图中拉出并删除了对这些查询的所有引用，页面在 3 分钟后不再崩溃，现在需要 7.5 分钟才能失败。
