我想制作一个包含一页的文档，该文档必须重复 10000 次。每重复一页，页面上都会添加一个唯一的编号（我不会在 MWE 中显示它，因为这不是我的问题）。
因此，我看到有两种方法：创建一个\makepage生成页面的命令，然后执行
\foreach\AA in{1,...,10000}{
\makepage
\newpage
}
或者制作单页 pdf 然后
\foreach\AA in{1,...,10000}{
\includepdf{page.pdf}
}
当然，第二个更快（451 秒 vs 279 秒），但时间并不重要。我想减少pdf 的大小（第二个较小：32356 KB vs 1905 KB -- 差别很大），另外我也不想遇到Tex capacity exceeded。
问题是：我能否从规模上让这个过程更加有效？笔记：我必须使用 LuaLaTeX。
更新：第一种方法（多次复制同一个页面）生成了 50000 个页面，没有崩溃，而第二种方法在生成 15000 个页面时崩溃，Tex capcity exceeded

答案1
这xsavebox包可以用来进一步减少最终的PDF大小，并大大加速由因素的三十。
包xsavebox\includepdf使用与其底层 LuaTeX 原语类似的技术，\saveimageresource以便将内容封装一次以供重复使用。然而，xsavebox允许封装任何排版内容，而不仅仅是外部图形/文档页面，以避免多次包含。此外，可以避免使用双文件方法（原始帖子中的第二种方法）。
xsavebox提供\xsavebox/ ，其用法与标准 LaTeX /命令\xusebox对非常相似。\savebox\usebox
此外，这种方法似乎没有内存问题（TeX 容量）。
\usepackage{xsavebox} \xsbox{MyPage}{\parbox{\textwidth}{\makepage}} ... \foreach\AA in{1,...,10000}{ \xusebox{MyPage} \newpage }
