Hello everyone.

I have one website, with many authors and a lot of posts/articles. I migrated from WP to Hugo about 6 months ago. To develop with Hugo, I just run `hugo server` or `hugo server --ignoreCache --disableLiveReload`, but the time of build is very long. See the statistics of Hugo below:

```auto
Built site for language pt-br:
0 of 1 draft rendered
0 future content
0 expired content
1771 regular pages created
3128 other pages created
0 non-page files copied
0 paginator pages created
240 authors created
1219 tags created
98 categories created
total in 25103 ms

```

I saw this video: [https://www.youtube.com/watch?v=CdiDYZ51a2o](https://www.youtube.com/watch?v=CdiDYZ51a2o)  
But I don’t have any tips to increase Hugo build performance. Can someone enlight me?

25 seconds is hardly “a lot of time” for all the work done here.

But …

running with `hugo --templateMetrics --templateMetricsHints` gives a few hints:

- You can save 777 ms by using partialCached for the sidebar partial, and you can probably also do that for the footer.
- You can save a lot by doing less work in theme/post/single.html – you need to look at the related feature in Hugo to replace the intersect construct. [https://gohugo.io/content-management/related/](https://gohugo.io/content-management/related/)

Wow!  
I tried to use the partialCached another time, but, without tips of --templateMetrics and --templateMetricsHints, I did not see any changes. Now, I’m using the partialCached in Header, Footer and Sidebar.

But, the tip of related feature is gold. Thank you a lot!

```auto
Built site for language pt-br:
0 draft content

240 authors created
1219 tags created
98 categories created
total in 2181 ms

```

Just to resume the changes:

- Modify the related posts script to original solution of Hugo
- Use partialCached in Footer, Sidebar and Header.

Just to know: I remove the Tags from my taxonomies. I realize that I use tags just to make the Related Posts. But, I configure the Related to take Categories first, title in second after authors. Removing the Tags Taxonomy, the build on the server got much faster. This decrease the number of `other pages created` from 3134 to 714.

This gives me more freedom to organize where I can use the partialCached without break some page information. In past post, I said that I was using partialCached in Sidebar and Header. Doing this, I can get just 2181ms to build in development environment, but I can’t use cached in this partials because the info in that areas changes sometimes. So, I rollback the `partial` default include, but the build increase to something like ~5000ms. Removing the tags like I said before, I get ~2500ms. Results:

```auto
Built site for language pt-br:
0 draft content
0 of 2 futures rendered
0 expired content
1779 regular pages created
714 other pages created
0 non-page files copied
0 paginator pages created
107 categories created
241 authors created
total in 2696 ms

Note that you can still use the tags values in related even if you don’t have a taxonomy configured for it.

Yeah. I’m using it, but with a small weight configured, since the categories is much to have taxonomy when authors write and tags don’t! 🙂

Thank for your help @bep.
