Are you sure it's just CPU? It may be bandwidth for the network device that is constrained - and the CPU is trying to figure out where to put all the packets.
Keep in mind, images (especially) are a lot of bytes worth of data. If your HTML is 10K, but you download a relatively small banner image - that can be 100K of additional data (e.g., more than 10X the workload). Of course that’s a lot more work for the system. A typical web page will have 10-20KB of "skeleton" framework, but could have several megabytes of images and non-HTML files. A multimedia page could have several times more of that if you include streaming resources like movies or sounds. -- Robin D.
