Improving Build Time

[finnlesueur]

Kia ora koutou,

Been using Hugo for a long time and loving it. I’ve got a Synology DS220+ at home I want to use as a (admittedly wimpy) CI build server for my website. My website is mainly blog posts about hiking - each post has a few images which I’m resizing with Hugo.

I’m looking to improve the build time, if I can. I see that Hugo stores resized images in resources/_gen for reuse on each build, great.

For this test I changed a single line on one post

Fast-forward
 content/posts/2019-02-06-mt-herbert/index.md | 1 +
 1 file changed, 1 insertion(+)

And then I ran my command to see how the build goes. It seemed to rebuild every single page, even though only one changed. Is there I way I can get Hugo to be more intelligent about this?

./hugo --verbose --destination="$HOME/CI/blog-build/" --debug

Many thanks in advance for any thoughts you might have!

Hugo cannot build your site incrementally when you run the hugo command. There’s some discussion of it here:
https://github.com/gohugoio/hugo/issues/1643

If I read the Synology specs correctly: 2-core 2.0 GHz. Ouch. I’d build locally and push the published files. Assuming your processed images and static files are each 200 KB, your published site would be less than 250 MB. And the Synology specs state “192 MB/s sequential write throughput*”. So it seems like this would be a much faster approach.

Ah, I understand the not building incrementally. That makes a deal of sense - it looks like quite the challenge!

If I output some metrics (which I just learned about) I can see it gets pretty hung up on the rendering of images using my figure shortcode.

Unfortunately, I have been using full-size images because I like having the highest resolution available. A typical image is perhaps 18mb which gets resized like so:

I resize it with a shortcode like this:

{{ $img := (index (.Page.Resources.Match (print (.Get "name") ".*")) 0) }}
{{ $img512 := $img.Resize "512x webp" }}
{{ $img1024 := $img.Resize "1024x webp" }}
{{ $img2048 := $img.Resize "2048x webp" }}

<figure
    {{ with $img.Exif }}
    data-lat="{{ .Lat }}"
    data-lng="{{ .Long }}"
    data-fig="{{ $img.Name }}"
    {{ end }}>
    <a href='{{ $img.Permalink }}' title='Full size image: {{ .Get "title" }}'>
        <img 
            srcset='
                {{ $img512.Permalink }} {{ $img512.Width }}w,
                {{ $img1024.Permalink }} {{ $img1024.Width }}w,
                {{ $img2048.Permalink }} {{ $img2048.Width }}w'
            sizes="(min-width: 780px) 584px, calc(100vw - 16px)"
            height="{{ $img.Height }}"
            width="{{ $img.Width }}"
            src='{{ $img.Permalink }}'
            alt='{{ .Get "title" }}'
            loading="lazy"/>
    </a>
    <figcaption>(📷: {{ if .Get "author" }}{{ .Get "author" | markdownify }}{{ else }}Finn Le Sueur{{ end }}) {{ .Get "title" | markdownify }}</figcaption>
</figure>

I suppose the only thing to do would be to not use full-res images? My website build output is 3.9gb.

I have previously been rendering locally on my laptop, but I’d like to use my Synology as a build server so I can write posts etc. from other devices like my phone or iPad where I’m not able to build locally.

Clearly I’m not going to lose out by waiting a couple minutes, but I thought it was worth asking.

What’s that? 72 seconds of your build.

That’s the layout template that generates my hiking blog posts. Makes a page like this: Lake Morgan | Finn Le Sueur. I can’t actually tell what is making that template so slow?

{{ partial "header.html" . }}

<div class="content">
    <h1>{{ .Title | markdownify }}</h1>
    <p>Activity Date: {{ with .Params.date }}<time>{{ time.Format "2 Jan 2006" . }}</time>{{ end }}<br/>
    {{ with .GitInfo }}Updated: <time>{{ .AuthorDate.Format "2 Jan 2006" }}</time>{{ end }}</p>

    {{ if ne .Params.statsTable false }}
    {{ partial "statsTable.html" . }}
    {{ end }}

    {{ .Content }}
</div>

<script>
    var GPXFiles = [
        {{ range sort (.Resources.Match "*.gpx") }}
            "{{ .Permalink }}",
        {{ end }}
        ],

        GPXDataFiles = [
        {{ range sort (.Resources.Match "*.gpx") }}
            "{{ $.Site.BaseURL }}/tracks/{{ index (split .Title ".") 0 }}.json",
        {{ end }}
        ];
</script>

<style>{{ readFile "/themes/hugo-finn/static/css/mod-gps.css" | safeCSS }}</style>
<link rel="stylesheet" href="/css/leaflet.min.css"/>
<script src="/js/leaflet.min.js"></script>
<script src="/js/Polyline.encoded.js"></script> 
<script src='/js/Leaflet.fullscreen.min.js'></script>
<link href="/css/leaflet-fullscreen.min.css" rel="stylesheet"/>
<script src="/js/multiHike.js" async></script>

{{ partial "footer.html" . }}

Try taking this out and see what happens.

It shouldn’t be there anyway. According to specs style elements must be inside of the head element.

[finnlesueur]

Ah, true, I had moved it to see if I could increase the non-blocking render time of my pages.

Taking it out doesn’t appear to have much effect.

Start taking out other bits, one at a time.

I notice that you’re ranging through the same collection twice. If taking out of them reduces time, you could consolidate into one range, appending to string vars with newlines, then dump the vars after ranging.

Also try taking out the .GitInfo access. Maybe that’s slugish on your NAS.

[finnlesueur]

Good thoughts. for the post/gps.html template:

1. Removing one of the loops has a negligible effect
2. Removing the .GitInfo has a negligible effect
3. Removing {{ .Content }} drops the rendering time to 17.06759274s (seems not negotiable though! Haha)
4. Removing the stats table partial has a negligible effect
5. Removing the readFile statement has a negligible effect

I’ll keep searching but I think it might just be something to live with.
