I use Structure for titles, breadcrumbs, nav, etc. I turned on debugging output, and it turns out titles (exp:structure:titletrail) and breadcrumbs (exp:structure:breadcrumb) are really performance intensive, taking my 1 second load to 2.x seconds, each getting the "warning/yellow background" in the EE load stack. Any suggestions on what I might do to tweak performance?
EDIT: The breadcrumb and titletrail tags now each add about 1.5 seconds to my page load time and 50MB in my template stack. I've since added several (like 200) more entries, making the total entries managed by Structure to several hundred. Oddly, the nav_advanced tag takes almost nothing.
Perhaps the amount of entries managed by Structure have something to do with this performance hit? I read on EE's Pages Module page that very few pages should be used with this. If Structure is based on Pages, does it also inherit this limitation?
