模拟RAM使用情况的工具

Question

在Windows 7（64位）中是否存在可以消耗一定数量内存的工具？

我想在可用RAM变低时测试软件的行为。

Sysinternals提供了一个名为TestLimit的工具，该工具由著名的Mark Russinovich提供。您可以从以下网址获得它：https : //live.sysinternals.com/WindowsInternals/，分别为32位和64位版本。

要分配1024 MB，您可以执行以下操作：

testlimit64.exe -d 1024 -c 1

并通过Ctrl+ 结束C。

以下命令行选项可用：

C:\Users\\...>testlimit64.exe
