Hello Quarto,

I'm wondering if there is a way to make Quarto (or Pandoc) use more threads/cores ?

I'm currently compiling a document to HTML (from R), and it takes more than 3 hours. The document is not that long: 2700 lines (more than half of those being text). There are no complex computations (the knitting in itself takes only a few minutes), but once it's done knitting, it will take close to 3 hours to output the HTML document (which is roughly 15MB in size).

During that whole time, only ~5% of my CPU is used by the Deno virtual machine, so I was wondering if there was a way to have it use more CPU resources to speed up the process ?

Thanks :)</div>
