我制作了这个文件：
\documentclass[uplatex, dvipdfmx]{jsarticle}
\begin{document}
\LaTeX
\begin{equation}
x^2 + y^2 = 5
\end{equation}
\begin{equation}
x^2 + y^2 = 13
\end{equation}
\end{document}
然后在 VScode 中构建该文件。
构建这么小的文件需要 10 秒钟。我觉得这花了太长时间，所以我问了这个问题。

这是我的.latexmkrc：
#!/usr/bin/env perl
$latex = 'uplatex -synctex=1 -halt-on-error -interaction=nonstopmode -file-line-error';
$latex_silent = 'uplatex -synctex=1 -halt-on-error -interaction=nonstopmode -file-line-error';
$bibtex = 'upbibtex';
$dvipdf = 'dvipdfmx %O -o %D %S';
$max_repeat = 3;
$pdf_mode = 3;
$pvc_view_file_via_temporary = 0;
为什么我的文件要花这么长时间才能生成？
是否存在消息[13:55:37] LaTeX log parsed with 0 messages.
瓶颈？
