Build time very slow (benchmark results)

Hello all,

I'm working on a project (developed by others) which basically retrieves data from a CMS and apply them to the frontend. During the frontend development process the local build time, upon save, is very slow (20 seconds slow). Even if that is a very minor change like adding a class to an element. I added the ---incremental flag on the dev build but this doesn't seem to make a big difference.

On the console I am getting the below warnings but I did not find anything related to them on the research so I can fix them.

[11ty] File changed: src/pages/main/documents.njk
[11ty] Writing _site/main/documents/index.html from ./src/pages/main/documents.njk
[11ty] Benchmark   2275ms  12%   796× (Configuration) "image" Nunjucks Async Shortcode
[11ty] Benchmark   1755ms   9%    37× (Configuration) "jsmin" Nunjucks Async Filter
[11ty] Wrote 1 file (skipped 37) in 19.21 seconds (v2.0.1)

Images are hosted in the CMS and they are cached (11ty default behavior).
Any clues on how to speed things up?

I’d start here: https://www.11ty.dev/docs/debug-performance/

This can give you further insight into what’s happening in your build.
