So basically it is the problem with CFG (exploit protection) which is not ready for the cases when there are many allocations and freeing of excutable memory blocks.

Kinda; mainly that NtQueryVirtualMemory was super slow when scanning over CFG, which was bug fixed in the April 2018 Windows 10 update. It also uncovered a "bug" (performance weakness?) in v8 that they were able to fix so less CFG blocks were allocated. So kind of a win/win in the end, bugs fixed, world a slightly better place.

They implemented a freelist, it's a common workaround for problematic allocators, but has its own issues (https://www.tedunangst.com/flak/post/analysis-of-openssl-fre...)

Hi Bruce. This is a fantastic article, but I needed to read it twice to understand everything. Very dense in information, and sometimes the order of things make it hard to follow. Sometimes you tell us what you did (e. g. modified the virtual memory scanner) before telling us why (what CFG is, how it works), which was confusing. > It turns out that reproducing the slow scanning from the sampling data was quite easy.…

I notice this sometimes in books or tutorials, that stuff you need for code to run is implemented later.

This isn't meant to be an especially religious comment, but I regularly switch back and forth between OSX and Windows 10 and wanted to make mention of the differences. I also use Ubuntu fairly regularly but only over ssh so I'll discount it from this comparison. Both OSX and Windows 10 do suffer from UI lag but, in my experience, it is far worse on Windows 10 to the point where I have come to absolutely detest Window…

This is strange. I run a 6 year old PC with win 10 on it. It has 4GB of RAM. I use an SSD and an M.2 drive. The thing is snappy as hell. I face zero lags, jitters, or switching delays at all. I get the feeling that writing things to disk is causing delays.

I run a 6 core desktop with 32G, and 1TB M2 SSD, and after an upgrade from Windows 7 to Windows 10 last Christmas, input lag in mintty terminals was dramatically worse. Even just holding down a key and observing the stream of characters at 15 per second or whatever my repeat rate is, it glitches and stutters.

That's not an option for mobile though..

Firefox have extensions on mobile, plus ads make websites heavier, and suck more bandwidth _____________________________ Says the person with +500 tabs on chrome android

I just kind of figured we'd stop having UI lag by now. I work on a 24 core workstation with 64GB of RAM and things lag all the time. Not slow to complete, like jittery key entry and non-responses. Haven't we figured out thread prioritization by now? Can't we make sure something draws 60 times per second while things are going on in the background? My Android Studio build should be totally isolated from my inbox. I kn…

Windows 10 is really inconsistent. I have it running in a VM on a Fedora host and it's snappy as hell. Also on a pretty basic office-spec Celeron, but then running it on a new Ryzen 7 sometimes it lags. I don't think it's directly related to the performance of the hardware, there must be something else going on.

You should try cinnamon. There's no accounting for taste, but after using gnome 3 for three years I tried cinnamon (version 3.6, older versions weren't good) and I found it better across the board.

Tried it with for my now very old netbooks (because 1024x600 is low-res now), kept it on my desktop machine because it's simple, out of the way and fast.

I love Cinnamon and run it on a few machines, and as soon as they sort out mixed DPI support I'll be switching back from Gnome on my main machine too. It's been a while since I've tested actually...

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.

When, and compared to what? I'm pretty sure it was never faster than Thunderbird let alone something like Mutt.

I don't mind so much when a single program that I'm using interactively has a pause, even though it's annoying as hell. What really bugs me is that regardless of how many cores I have, there is always one pegged by that annoying background service. If I start up windows, you can bet that windows update will first peg a core for a few minutes. Then the builtin windows antiviris takes over (perhaps because win update w…

Analytics about you and your machine won't get collected by themselves. Have you noticed this phenomenon with free software?

It's everywhere. Simple example: Compare the differences--and even the subtleties--in information density between yahoo.co.jp and Yahoo.com.

Oh wow that is a stark contrast. yahoo.co.uk, yahoo.co.in, yahoo.co.id, etc. are all incredibly low-density as well. I have always loved the Japanese aesthetic, I wonder if any other cultures have a similar preference for websites.

Only downside being that it's common to see people walking around in Japan with their phone about a foot in front of their face.
