If you're running any kind of intensive database I/O and your databases are larger than RAM, then look for a dedicated server. It tried switching many VPS offerings, but there are always bottlenecks when you share the disk I/O with everyone else. For example, on one provider, I had problems that everyone is placing some heavy cron jobs at midnight and completely kills the disk I/O for 10-15 minutes.
