i have also disabled all my plugins. and changed some advanced settings of the mediacleaner plugin to make it slower. i have deleted many POST TYPES (USED BY THIS INSTALL)
Now i only have these.
attachment (165217), custom_css (2), nav_menu_item (26), oembed_cache (1), page (10), post (3783), tdb_templates (33)
when i deleted many of these. now it stays at 0 posts not to 200 posts processed anymore.
I use Xampp and use localhost only so no public webpage.
my apache gives this result:
