Is it normal for CPU/Disk usage to increase for a few seconds after loading a new page on Chrome/opening a program, or not at all? For example when I load a new tab on chrome and I search for something CPU usage goes from 3% to like 50% for 2 seconds then goes back to 3%. Same with disk usage, goes from 0% to like 40% for 2 seconds then again back to normal. I check it on task manager.



Is this normal/fine?
 
If you think it's excessive, a lot of antivirus and anti-malware programs (including the default Windows Defender) now inspect websites before they allow your browser to access them. That's good in terms of protecting you, but can substantially slow down the browser. You can turn off this functionality if you wish.
