Great article! The only thing I wish was explained a bit better was the 2 TiB CFG memory reservation. What's that for, again?

Basically, one byte of CFG memory "controls access" to 64-bytes of executable memory - indicating which addresses are valid indirect branch targets. With appropriate compiler and OS support this can help stop some exploits.

Unfortunately it quickly gets really complicated so a bit of hand waving is necessary.

Every other paragraph the ad box tries to run a full screen video with unmuted audio by default. I got headache some half way thru article and then gave up reading. From authors work, it doesnt seem this particular blogger needs my two cents from ads he runs to live a decent life. Its sad how the state of internet looks like these days ;(

That was a lot more interesting than the "man, bloatware" complaint I was expecting from the title.

Gmail and Inbox both hang for me on my Chrome on Linux with almost no load.

It's funny how tides turn. Initially Gmail was the king of performance.

“I work on Chrome, on Windows”

...

  chrome_child.dll (stack base)
  KernelBase.dll!VirtualAlloc
  ntoskrnl.exe!MiCommitVadCfgBits
  ntoskrnl.exe!MiPopulateCfgBitMap
  ntoskrnl.exe!ExAcquirePushLockExclusiveEx
  ntoskrnl.exe!KeWaitForSingleObject (stack leaf)

So don’t use a proprietary kernel that performs poorly?

Uggh. I'll talk to wordpress. They were supposed to turn off the video ads. I agree, it is sad.

If you hate ads, and you hate the state of the internet, run adblock.

Seriously. Adblock is the way you have to fight back, to change the economics of the internet. Install it, use it indiscriminately, and make sure you tell others to use it.

My company makes a decent chunk of money from ads btw. Not because we can't make money another, better and cleaner way, but because it makes no sense to leave money off the table when the adblock rates are so low.
