Will this supplemental Navigation code slow down performance?

[SidFeyDesigns]

I was curious is the following code will hinder performance in any way. If so will the Transients Module help in any way?

<mvt:do name="l.result" file="g.Module_Library_DB" value="Category_Load_Code( g.Category_Code, l.settings:current_category )" />
<mvt:do name="l.result" file="g.Module_Library_DB" value="CategoryList_Load_Parent( l.settings:category:parent_id, l.settings:sub_categories )" />
<mvt:if expr="l.settings:category:parent_id GT 0">
    <div class="column whole np mtp1-25 mbm1-25 print-hide">
        <div class="h2">Shop Related Categories</div>
        <div class="row bottom-shadow o-layout u-grids-2 u-grids-3--xxs u-grids-4--xs u-grids-5--s u-grids-6--m sub-category-layout">

Not terribly so, but, unless this changes by customer/inventory or something else in 'real time', why not just make it a static resource you can call?

If it needs to be quasi dynamic (i.e., changes daily), put the bulk of this code into a Marketing feed, set it to regenerate daily, and then just use File_read() to bring in the contents?
