As an engineer I need to tune my laptop to run at its best performance. Why? The answer is why not.

My laptop is pretty old. It's at least 7 years old. (I bought it from the 2nd market.) Its memory capacity is 8GB. And cpu? It's Intel(R) Core(TM) i5-4210U CPU @ 1.70GHz (2 cores x 2 threads)? This is just enough for daiyl web surfing... until it isn't.

As the laptop CPU can be adjusted to use much or less power, here comes CPU Power policy. When my browser is running the laptop really needs CPU Power policy set to Maximum Speed. This would be fine as long as the external power source is available. The CPU fan will work accordingly :)

$ terragrunt --terragrunt-parallelism 1 apply
$ nice -n 19 terraform -parallelism 1

I'm using Enlightenment. I've been using it. Since 2011 or even before that, I don't remember =))

My Enlightenment setup is a nightmare, in some situation it consumes quite a lot of CPU. Switching quickly to xfc4 really helps to save the Earth.

Why don't I uninstall Enlightenment? I think it'd be some problem hidden with my setup, and I haven't found it. What I tried in the past

• Pinned version: Use Englightenment 0.23.x instead of the latest version. It worked for a while.
• Fixed all troublesome keyboard/input issues (yeah my keyboard/touchpad is kinda broken and it generates quite a lot of annoying events and they can slow down the system at the same time.)
• Traced some problems down to... nowhere.

Most of the time I can't read/view two tabs at the same time, and my eyes wouldn't be faster than any cpu unit. When I slow down firefox I still see the same results. It's interesting that the defaults settings are very high and really make firefox hang on my laptop.

• dom.ipc.plugins.processLaunchTimeoutSecs=1
• dom.ipc.processCount=1
• dom.ipc.processCount.webIsolated=1
• dom.ipc.processCount.webLargeAllocation=1
• dom.ipc.processPrelaunch.fission.number=1
• javascript.options.concurrent_multiprocess_gcs.cpu_divisor=1

FIXME: It's said on some threads that Google's browser doesn't have any option to reduce the number of cores they are on. It may be wrong but only would I use such browser for some rare situation, so not a big deal...

The world has changed. Web owners don't want to waste their money and they force web browsers (aka their clients) to use more and more resources. Some web owners don't serve if you don't have javascript, the cpu&memory killer.

So let make that behavior default.

• NoScript
• Cookie Autodelete
• AdBlocker Ultimate
• uBlock Origin
• Ghostery (automatically rejects almost all cookie consent questions in EU)

Note: I have AdGuard AdBlocker on firefox mobile version

• htop. Look at cpu usage, which is often indicating the source of the problem on my laptop. It's either Enlightenment or Firefox
• iostat or vmstat for fun :)
