In my Java project I use the Excel-FrameWork "SmartXLS" to calculate Excel files.在我的 Java 项目中，我使用 Excel-FrameWork“SmartXLS”来计算 Excel 文件。 http://www.smartxls.com/indexj.htm http://www.smartxls.com/indexj.htm

To do this, the file is filled with values and then these are calculated using the method:为此，文件中填充了值，然后使用以下方法计算这些值：

workbook.recalc();

This all works well.这一切都很好。 The only problem is when the file contains several sheets and a lot of formulas.唯一的问题是当文件包含多张工作表和大量公式时。

In my concrete problem case I have a file with 11 worksheets and about 50000 - 60000 single formulas respectively calculations.在我的具体问题案例中，我有一个包含 11 个工作表和大约 50000 - 60000 个单个公式的文件，分别计算。 The file is about 3.5MB in size.该文件大小约为 3.5MB。 The time for the calculation is between 5 - 7 seconds (workbook.recalc()).计算时间在 5 - 7 秒之间 (workbook.recalc())。

I realize that in Java you probably can't reach the speed of calculation as when Excel runs native for example in a Windows environment.我意识到，在 Java 中，您可能无法达到 Excel 原生运行时的计算速度，例如在 Windows 环境中。 To reduce the size of the file I have already reduced the formulas to a minimum.为了减小文件的大小，我已经将公式减少到最低限度。

Do you have experience with SmartXLS?您有使用 SmartXLS 的经验吗？ Are there any tips and tricks to speed up the calculation?有没有加快计算速度的技巧和窍门？
