Z12 Performance Of Serve Content Changes

Support
1

Now we’ve been able to migrate our site to a working V12 (subject to 12.1 fixes) we’ve been using it as part of our content production and we’ve noticed that performance when editing content, with the new hashtable approach to HTML, is really slow.

Zola 11 Serve

After the initial build Z11 is slow but the changes after that to markdown are in ms.

That’s expected, the new approach rebuilds the whole site to avoid all the weird bugs the smart rebuild had. To get back roughly the same speed you had before, use zola serve --fast that will rebuild only the page that changed.
