I have a massive amount of entries of wpdmkey like
__wpdmkey_5718e3fa184da
in the wp_postmeta slowing my page down to 20-30 Seconds for a Page Load.

I am on Version 4. Preparing an Update to 7. Still need to fix the speed issue for my customers.

Is it save to delete the wpdmkeys in the DB? They are recreated on each download.

Hello,

Thanks for reaching out.

wpdmkeys are usually generated automatically when a new download request is made.
You can delete those but a few recommendations before deleting,

– Try clearing cache and stats data from Settings > Privacy Tab(available in v4.5.5 or higher)
– Take a full database backup first.
– Remove older keys instead of deleting everything at once.
– After cleanup, optimize the wp_postmeta table.

Upgrading to Version 7 will help significantly with performance and database handling as well.

Regards
