help wanted
説明
I recently came across this question on SE, where someone has managed to make pdflatex much faster (particularly for large documents) by "pre-compiling" the preamble. The accepted answer mentions that there's a package mylatexformat that can assist in this process. I was wondering if you thought it might be a feature worth introducing to tinytex? I wonder, also, if a similar approach might work with xelatex, as that compiles noticeably slower than pdflatex, although I don't really know why so maybe this won't help.
