问题 (The Question)
SuperUser reader learningAsIGo wants to know if there is a way to limit Microsoft Excel’s CPU usage while running a VBA script on his computer:
超级用户读者的学习AsIGo想知道是否有一种方法可以在计算机上运行VBA脚本时限制Microsoft Excel的CPU使用率：
Is there a way to limit Microsoft Excel’s CPU usage when it is running? I have a VBA script that calculates a large amount of giant array formulas. The entire set of calculations takes approximately twenty minutes to complete and uses 100 percent of my CPU. I am unable to use my computer during this time and would rather have Excel ‘running in the background’ while using about 50 percent of my CPU’s capacity so that I can continue to do other things.
有没有办法限制Microsoft Excel在运行时的CPU使用率？ 我有一个VBA脚本，可以计算大量的巨型数组公式。 整个计算过程大约需要20分钟，并且会占用我100％的CPU。 我在这段时间内无法使用计算机，而是希望Excel在后台运行时使用大约50％的CPU容量，以便我可以继续执行其他操作。
Any suggestions? My computer’s operating system is Windows 7 Enterprise 64-bit with a 2007 32-bit version of Excel installed on it.
有什么建议？ 我的计算机的操作系统是Windows 7 Enterprise 64位，上面安装了2007 32位版本的Excel。

答案 (The Answer)

超级用户贡献者mtone为我们提供了答案：
If a VBA function is called from several formulas or if your script generates or forces the recalculation of several formulas, then this should definitely make use of the multi-threaded calculation feature in Microsoft Excel. Respectively, this would either run multiple instances of your VBA function for each formula, or recalculate multiple cells simultaneously while your VBA script is running on a single thread.
如果从多个公式调用了VBA函数，或者您的脚本生成或强制重新计算了多个公式，那么这绝对应该利用Microsoft Excel中的多线程计算功能。 分别地，这将为每个公式运行VBA函数的多个实例，或者在VBA脚本在单个线程上运行时同时重新计算多个单元格。
You can limit the number of threads used by Excel to recalculate formulas by going to Options and selecting the Advanced Section, then scrolling down until you reach the Formulas sub-section.
您可以通过转到“ 选项”并选择“ 高级”部分 ，然后向下滚动直到到达“ 公式”子部分 ，来限制Excel用于重新计算公式的线程数。
