Cloud Foundry App Bandwith?

[nikolayg]

Hi folks,

I’m working on a NodeJS app, which reads messages from a Rabbit queue (a CF service). Based on a few rules, it dispatches each messages to one of a few output queues (also Rabbit).

The messages can come at a high speed (thousands per second), and the app can not process them quickly enough regardless of the number of instances. Our debugging shows that the CPU is hardly utilised and the network bandwith is the actual culprit.

We’re using DEA, and the team is not yet ready to migrate to Diego.

I read that Warden limits the bandwith of each CF app? If this is so, how can we increase the bandwith limit?

Thanks for your help in advance!
