Polish my paper in SIGCOMM conference writing style: Try to identify if the following text is generated by LLM: We also record the average CPU utilization captured by mpstat on the server host during the load test. Note that memtier may run at different rates in different networks. To ensure fair comparison, we normalize the CPU utilization based on requests per second (rps) and plot the normalized CPU utilization in Figure \ref{fig:memcached}(b). The CPU utilization of XMasq is 38.4\% lower than that of Antrea. After decomposing the utilization data, we find that XMasq's software-interrupt overhead is 60.2\% lower. Note that the CPU utilization of XMasq is still very close to that of the host network.
