I received a 'love letter' from my hosting provider: you have too many tables in your databases and are negatively impacting performance. You have 14 days to correct this or we will take your firstborn...or something to that effect. Mind you, my account comes with unlimited domains and 25 databases. I had about a dozen databases, but with almost all of them being Drupal that put me well over the 1000 table maximum they had introduced since I had signed up.
The time had come, the rhino said, to think of many things, a VPS to call my own despite the stress that brings.
