>I've noticed what seems to me some unusual behaviour. When I visit the site I see a left pane with navigable table of contents, and the right pane shows the contents of the current selection. Initially CPU utilization is very low. This is all as expected.
>If I navigate the left pane, CPU remains low. However, as soon as I click on any topic CPU jumps up to about 30% on my quad core machine and remains there as long as I have the site open. After the initial page load I would normally expect CPU to drop back down to a low level.
>I see this in current versions of Firefox and MS Edge on Windows 10.
>Is this known/expected behaviour? I ask because there is a type of malware which, when injected into a compromised site, causes visitors' computers to mine cryptocurrencies. This manifests as unexpectedly high CPU utilization.

I can verify high CPU load under the points above. it's not 30% flat, it's a lot of 100% peaks in 4 cores of the i9 I use. there is also higher load on net traffic while the page looks like loaded.
