> I ran a produce-only workload on a plaintext single broker. One of the main
> findings was that
> kafka.network.Processor.updateRequestMetrics(kafka.network.RequestChannel$Response
> method is expensive to the extent that 90% of the time taken by
> Processor.processCompletedSends() is taken by this method.
> The flamegraph is attached.
> The objective of this ticket is to optimize the performance of metrics
> collection here.
