The `partialCached` template function can offer significant performance gains for complex templates that don't need to be re-rendered on every invocation. Here is the simplest usage:
```
{{ partialCached "footer.html" . }}
```
You can also pass additional parameters to `partialCached` to create *variants* of the cached partial. For example, if you have a complex partial that should be identical when rendered for pages within the same section, you could use a variant based upon section so that the partial is only rendered once per section:
{{<codefile="partial-cached-example.html">}}
{{ partialCached "footer.html" . .Section }}
{{</code>}}
If you need to pass additional parameters to create unique variants, you can pass as many variant parameters as you need:
