Slow Build Performance or Bad coding?


#1

Hello Hugo community,

I just ported a wordpress site of 2500 pages to Hugo CMS .

Here is the finished site – https://www.wktvusa.com/ (custom style based on bootstrap 4) and here is all the code https://github.com/fieldingtron/wktvusa

Im getting what I think are slow build times like 10 minutes from build to deploy via netlify

here are my hugo – templateMetrics

Would anyone have an idea where I am not coding correctly ? I have tried to use Cached Partials but without much effect

Template Metrics:

     cumulative       average       maximum
       duration      duration      duration  count  template

I assume you resize 2015 images on every build, which is going to take time.

What I recommend is that you:

  • Run hugo locally
  • Commit the content of /resources/_gen/images to GitHub
  • A related tip: hugo --gc will clean up unused images in that folder.

Thanks BEP

That really made a big difference as in it dropped 8 minutes off the deploy time on Netlify


Change file name for resized image resources
