For a custom post type I added a custom taxonomy which contains 20k+ terms. This is causing some serious performance issues for both the custom post type edit screen (which should be solved removing the default category metabox and adding a custom metabox)
However I am not sure how to solve the slow custom post type overview page. This page seems to also load all custom taxonomy values. So following question concerning this issue:
Is it possible to disable the load of the custom taxonomies on the custom post type overview page? What are the implications of removal of these values here?
