Performance improvements relative to... what?

We do get a surprising number of people who are upgrading from SQL LIKE queries. In a situation like that, you might see queries that take a few seconds to scan through a table in SQL get cut down to a few dozen milliseconds to fetch results from an index. That's just a good example of using the right tool for the job.

It would be a little tricky to compare performance to self-hosting, given the myriad of variables involved. And as far as other services go, perhaps someone else can speak to that. Or maybe you have a more specific scenario in mind?
