我正在使用 WSL 2（Ubuntu 20.04）和 Windows 终端设置将 markdown 文件编译到 beamer 演示文稿中。不幸的是，如果我尝试使用 pandoc 2.5 来编译它，编译时间会超过 30 分钟（无论是通过 pdfLaTeX、XeLaTeX 还是 LuaLaTeX）。在编译过程中会占用大量内存（有时超过 7 Gb）和 CPU。我现在正在使用完整的 texlive 安装，如果我编译最小的 LaTeX 文件，在 pdfLaTeX 上大约需要 7 秒，在 XeLaTeX 上大约需要 11 秒。我试图检查在 /mnt/c 和虚拟分区中的编译是否存在差异，但我没有看到任何差异。
当我跑步时，--verbose它往往会在那里停留很长时间：

markdown 文件只是：

我使用这个命令作为最小示例（这个特定示例持续不到 4 分钟，但我认为它不应该花费这么长时间，稍微大一点的 YAML 标头可能需要超过 30 分钟）：
pandoc -t latex test.md -o test.pdf
