That basically looks like it’s run out of CPU, so there’s hard choices to make over CPU allocation.  Cake isn’t responsible for that allocation, though it *might* be possible to optimise its use of the CPU a little further.

If you can obtain a CPU profile of that workload on that hardware, that might help to direct those efforts.
