While I agree that burst size spread is important for comparing CPU usage and capacity, the 'record_burst_stats' is a test_pmd specific feature. Applications may implement something different. > > Is it possible to incorporate it into this framework? We all agreed on CPU usage metrics for this patch, so let's limit ourselves this time. If we want more performance metrics, such as RX and TX burst size spread, they can be proposed and discussed in a separate RFC. It might trigger a lot of discussion, like the original lcore busyness patch that inspired this patch series.
