Header template extremely inefficient with many pages

[klieret]

I am considering a case where I have many pages (most of which will be excluded from the header by a solution such as https://mycyberuniverse.com/exclude-pages-from-navigation-menu-in-jekyll.html).

However, the build time per page increases the more pages I add (to more than 1s per page!).

I had initially reported this here: jekyll/jekyll#8066 and with the help of @ashmaroli traced that back to the header.html inclusion.

The linked issue also has a quick snippet to test this, generating a larger number of random pages.

You can keep pages off the header by not adding title in the yaml - does that help?

Yes, this is also what I did in the end IIRC, but it has been a long time and I'm no longer too familiar with this. Let me close this issue, if it affects someone else, they can reopen.
