databases..

I was talking a bit today about my mongoDB instance in mongoHQ being slow.

I need to make sure it is slow.

A friend who is a big advocate of App Engine recommended using that, and when I complained about it not supporting node.js, he said "no, use App Engine as a database". That's an interesting idea.. probably not for the scale of stuff I'm doing right now.. but I wonder how many requests per second App Engine's Datastore can handle..
