> When a task is receiving data at a higher rate than it can process, the task
> is back pressuring preceding tasks. Currently, there is no way to tell
> whether this is the case or not. An indicator for back pressure is tasks
> being stuck in buffer requests on the network stack. This means that they
> have filled all their buffers with data, but the following tasks/network are
> not consuming them fast enough.
> A simple way to measure back pressure is to sample running tasks and report
> back pressure if they are stuck in the blocking buffers calls.
