Hi guys:

As we known Hugo snippet support use `-` character trim space, it’s useful generate pretty code of HTML. But I want to know is there will make hugo generate site static code more slower?

As below code sample:

 ![image](https://canada1.discourse-cdn.com/flex036/uploads/gohugo/original/3X/e/f/ef5b66a81f03e109968672528294fd8901583f30.png)  
Question: Those code with `-` character will make generate speed more slower?

How about your think?

Have never noticed any difference, and that’s in a repository with hundreds of files.

Not yeah, the theme source files is small under hundred, but if the content files of blog articles too much, I think the generate speed would be slow down.

> But I don’t know about Go language, so can’t make sure is the block `{{- /* Some logic */ -}}` slower than `{{/* Some logic */}}` , maybe some can help me find the answer, thanks.

I wrote a simple benchmark.

```go
var t1 = template.Must(template.New("t1").Parse(`"{{23 }} < {{ 45}}"`))
var t2 = template.Must(template.New("t2").Parse(`"{{23 -}} < {{- 45}}"`))

```

**The difference in build time is noise.**

I have a 10,000 page site. Each page is rendered by layouts/\_default/single.html, which has 100 of these:

```auto
{{- if true -}}

  {{- .Title -}}

{{- end -}}

```

That’s 3 million of these `{{-` and another 3 million of these `-}}`.

I built the 5 site times, with and without whitespace removal.

| &nbsp; | With `{{ }}` | With `{{- -}}` |
| --- | --- | --- |
| Minimum | 4875 ms | 4891 ms |
| Maximum | 5201 ms | 5676 ms |
| Average | 5015 ms | 5111 ms |

@razon @jmooring  
Thanks for your code, there look seems the code block of `{{/*some logic*/}}` were more better. But not matter it’s smaller different not much effect.

> Hope this post would help more people who notice the generate speed under Hugo engine.
