I've noticed that a lot of sites will end up using 100% CPU usage on their Chrome tab. I haven't investigated, but I do wonder what sort of faulty design leads to this. You occasionally hear talk of sites using your CPU to mine cryptocurrency, but I'm more inclined to suspect lousy programming. I sometimes wish I had an easy way in Chrome to restrict a tab to, say, 5% CPU, for the cases where the CPU usage is clearly not adding any value. Just so I can get through an article without the fan ramping up.

renice 19 ?

  It's my understanding that renice doesn't limit CPU usage, but rather adjusts the process's priority in the scheduler relative to other processes. So I don't think it would stop a process from eating up all available idle cycles, draining the battery, and ramping up the fan.

    Also, I don't think there's a trivial way to get the PID of the process handling a particular tab.

      In Chrome, Task Manager shows PID along with CPU & memory usage.
