High CPU usage with only one app user


I’m trying to get some insight in the CPU usage of my application. So I took a profile with Kadira (https://ui.kadira.io/cpf/AqhRFqeoeCQJQW5Nm)

I’m seeing a high ‘Parsing incoming MongoDB documents’ percentage, but I’m not really sure what I should make of this… how can I find out why it’s being called?


looks like it is having a hard time parsing the incoming docs. What are you trying to do with it? what data are you sending it when this happens? looks to me as if it is quite a lot…

I think it might have been poll&diff… I’ve migrated my database to compose.io, and the high CPU usage is gone.

Current setup: Digital Ocean + Compose.io + Kadira (&deployment with mup)
