Okay, so I need to classify this bug report: "High CPU usage on network traffic on Apple laptops". The possible categories are mistranslation, assembly, other, device, graphic, socket, network, KVM, boot, vnc, debug, files, permissions, performance, kernel, peripherals, hypervisor. First, the issue is about high CPU usage related to network traffic. So it's something that happens when the system handles network data. High CPU usage suggests a problem with how resources are being used, possibly in the networking component of QEMU. Looking at the categories, 'network' seems directly relevant here because it's about network traffic causing high CPU usage. The other categories don't fit as well: 'socket' is more specific and might be part of network but not the main issue; 'performance' could be a consideration, but since it's specifically network-related, 'network' is better. So I think the correct category is 'network'. network
