I have a lot of entries on the wp_options table for _transient_timeout_gad_cache_
From what I read on the web, these are cache from Google Analytics Dashboard, but, despite the fact they should be deleted after a period of time, they stay there forever.
I suppose some slowness in my server is because of these db that grows with no sense (50MB for a single blog).
Do you have any easy fix for this?
