The autosuggest procedure can slow down your WordPress wp-admin interface quite a lot when you have a huge amount of terms.
Sometimes it’s useful to just disable this feature to make wp-admin more responsive. You can do this by adding
the following to your functions.php file
add_action( 'admin_init', 'deregister_autosuggest' );
function deregister_autosuggest() {
if ( is_admin() ) {
wp_deregister_script( 'suggest' );
}
}
