Question

因此，我有一个脚本，该脚本旨在将一些非常大的（700mb）txt文件发送到我们使用的服务的FTP，该服务会自动设置整个网域的价格。

我正在使用一个bitearray（如此处所示）将其上载到站点，并且我有一些非常基本的内置错误处理以及一些数据库绑定。

如果我们分开运行它们，它们的运行速度很快。无论出于何种原因，在完成一个程序段之后，直到开始另一个程序段的时间都是不稳定的。有时是2分钟，有时脚本会停顿40分钟，然后再移动到下一个块。

我有点假设问题是我正在为事情做更多的整理工作？还值得注意的是，即使停止脚本有时也需要15分钟。（例如，如果我只是在脚本运行的中间点击了break，则可能需要15到20分钟的时间才能停止）

此外，就其价值而言，该脚本在最近几天的运行时方面变得更加糟糕。我不知道我们可以做些什么改变，以使其开始花费更长的时间，但是我们已经到了。

无论如何，任何见解将不胜感激。

注意：清除变量时不会清除内容变量，应该吗？我应该保持开放吗？我认为我做不到，因为我正在使用不同的用户名连接到FTP。

这是代码（我实际上有大约12个* .txt块，但是它们是相同的，因此在这里将其减少到3个）：

我认为没有人会调试该代码。最好的选择是找到问题所在。我使用如下秒表。对其进行策略性设置：

$SW = [System.Diagnostics.Stopwatch]::new()
$SW.Start()

#Your code block goes here
Write-Host "End of Code block 1"
$SW.Elapsed.TotalSeconds

#Another code block goes here
Write-Host "End of Code block 2"
$SW.Elapsed.TotalSeconds

现在，如果您尝试突围并且花了15分钟才能做出响应，则可能是在进行操作时卡住了。在操作完成或失败之前，它无法响应。

似乎不应该花很长时间的Powershell脚本吗？
