Meteor.com slow?

I have a dev app deployed on meteor.com, and things are running real slowly the last couple of days.

what tools are people using to look into debugging this type of stuff before going to a production env?
Is there a way to deploy in “development mode”?

mongo command line provides the following info, which I think is very low usage for an app, can anyone comment?

datasize of 5,526,596 ~= 5GB …
i’ve also noticed that command completion on meteor’s cmd line is very slow.

 db.stats()
