# Latency loading Second Level Terms

 * The latency between selecting the first level custom taxonomy and the loading
   of the corresponding second level terms is too large; on ios the problem is even
   worse. Is there a way to load the second terms on “page-load” (like the first
   level custom taxonomies) to solve this?

 * The “first level” terms are loaded on page load since they’re set by the user
   in the WPUS settings, and it’s really easy to get a list of them quickly. i.e.“
   Category” “Custom Taxonomy 1” etc.
 * “Second level terms” are much more difficult because each “first level term” 
   could have dozens or hundreds of second level terms beneath it, and these need
   to be pulled from the database. We chose to not load these on the initial page
   load because it would slow down every page load, even when users weren’t there
   to perform a search.
 * What we plan to do in the future is to create a basic caching mechanism where
   the first time the second level terms are loaded, they’re saved to a list that
   can then be recalled instantly on subsequent page loads. We understand that this
   is going to be a very important feature for a lot of people, but it’s going to
   take a little while to get it right.
