For locally you can Kadira Debug:

Thanks. I’m trying kadira right now.
Is there a way to profile one specific transaction where I’m experimenting a slow down in a template load?

You can monitor how much ‘related’ DDP tasks took.
So method calls and subscriptions.
Related means that you check how is method called and check that name in kadira.

I’d actually need something more end to end and client centric. Is there anything within the framework itself to instrument the process steps?
