What are your thoughts on Arch Linux? Please include a few pros and a few cons, along with your overall impression of the operating system. Install Linux onto your Chromebook. Dual-boot alongside ChromeOS for maximum flexibility. GNU GRUB (short for GNU GRand Unified Bootloader) is a boot loader package from the GNU Project. GRUB is the reference implementation of the Free Software Foundation.

Optimizing Linux for Slow Computers. It's about Responsiveness, not performance! Most people's concerns are first about performance, and this is a mistake. Linux is plenty fast, but for many people it doesn't feel like so in the Desktop. When tuning a server, you'll really want to tweak for performance and high throughput. That's where most Linux configurations really shine over the competition: they come better tuned to get the most out of server configurations.

But in a Desktop you don't want that. For example, you're copying a 2. GB file to your old USB thumb drive, or you're unzipping a large file, or you're compiling that large package from source, or you leave Dropbox in the background syncing gigabytes of files from their servers. Or you're doing . If something needs to happen in a certain frequency, it doesn't matter if each cycle takes 1 second as long as it consistently takes the same 1 second - in all deadlines.

If you have a . And for media creation, it's a disaster. There is hard real- time where one peak or valley can be considered a catastropic failure, and soft real- time where you can handle a few peaks, but not so much. Hard real time requirements are rare, unless you're developing systems for nuclear plants you may miss a few deadlines. Most responsiveness issues are related to soft real- time situations. You can handle a few sparse peaks here and there, but no more than a few. And this is how you should do your research: not Googling for . And for the same reason, it's poor server OS.

Extensive tutorial about how to setup and configure GRUB 2 (version 2, the next generation) bootloader with multiple operating systems, including GRUB legacy and GRUB.

You will notice that the default Quicktime screen recording is super smooth, you rarely see stutters. But you don't need to use an audio specific distro or a hard real- time kernel. Critical audio distros don't use Pulse. Audio, but normal users will not be so concerned about it.

Optimizing Linux for Slow Computers. 2017 January 17, 18:15 h - tags: linux kernel arch. I've been researching a lot about Linux on the Desktop these days as you may. Share on Facebook. Share on Twitter. Share on Google+. You’ll need this. To dual boot Windows 8 and Linux you’ll first need Win 8 (duh). Download it from windows. Explain how to edit Grub2 and GRUB boot loader configuration file Menu.lst. Comprehensive guide to installing Windows 8.1/8/7/XP and later when you already have Ubuntu/Linux installed. Let's install Ubuntu first then Windows.

We can tune it to find a good balance between responsiveness and performance. If you really want to go hard- core, you may want to read the Linux Audio Wiki on Real Time, but it's out of the scope of this article. What are the real Bottlenecks? A . I am doing my tests on a very old Lenovo Thinkcentre Edge 7. It has an old 2nd generation Intel Core 2.

Ghz 4 cores Sandy. Bridge CPU. We just saw the release of the 7th generation Kaby Lake processors, so one might assume that nothing would run on such an old CPU, but you would be wrong. CPU is usually not serious a bottleneck unless you're doing really intensive computation, such as video compression, data sciences, genetics, neural networks, etc. Bentley Microstation V8i Ss3 Download Google here. For a casual user or even a heavy- weight developer, any processor better than the 1st generation Intel Core series is plenty.

GPU is also rarely a bottleneck unless you're doing heavy gaming or 4. K renderings. Most of the time you don't really need a USD 7. GTX 1. 08. 0. By the way, this is not necessary for most systems, but just to be on the safe side do this: 1. S mesa- demosglxinfo . If not, refer to your distro documentation, because this means you're not compositing through the GPU and you're wasting CPU cycles rendering your screen! If you try to measure your CPU and GPU usages, you will realize that most of the time they are actually idle!

That's right, you're mostly underusing your machine cores. The bottleneck usually boils down to I/O. RAM vs SWAPNow, you're opening your shiny Chromium browser. Us 1 0 Gta Sa Crack Dealer.

Anyone fooling around for a few minutes will open an average of a dozen or more tabs, without breaking a sweat. It's super easy to eat up all 8. GB of the average machines. Whenever that happens, the OS will have to start offloading data to disk, which is orders of magnitude slow. If application data is offloaded to disk and you alt- tab to it later, the OS will reach a .

And again, this will have the effect of blocking your actions. The environment may stutter for a second or more, making it unresponsive. The very first thing you may want to do is install an extension such as The Great Suspender. It will simply close all tabs but the one you're reading right now. When you change to another tab it will reload it. The effect is that you're not using RAM if you really don't need to. This extension alone can save you a couple of GIGABYTES of RAM, which is no small thing if you have 8.

GB or less. The other thing to consider is that Linux comes pre- configured to balance out offloading application data to swap to accomodate filesystem cache. So, if you're unzipping a large file, some of that data will go to RAM cache and application data will move to the disk. After you finish unzipping, you alt- tab to applications and boom: page faults, unresponsiveness. So you want to configure the OS to more aggressively keep your application state in RAM, and this is how you do it: 1. EOFvm. swappiness=1vm. This is how you tweak it: 1.

EOFvm. dirty. It increases performance at the risk of putting your data in risk of corruption. Schedulers. Why was . You have to thank Con Kolivas, Ingo Moln. The Linux kernel development is known to be super difficult to deal with and Con Kolivas is one of its victims, but his work live on to allow us to have better Desktop experiences these days. There are Process Schedulers and I/O Schedulers. The first is responsible to manage the Preemption of the kernel, how it switches between different computational tasks, the low- level equivalent of you .

For the most part you will be dealing with the Completely Fair Queueing (CFQ). Most development on this side is attributed to Jens Axboe, also responsible for the Deadline Scheduler and Noop Scheduler. Then there is the controversial evolution called Budget Fair Queueing (BFQ). When you have SSDs (and this is why you want SSDs), you will more likely choose NOOP (or Deadline) just because there is no need to waste computation time managing complex I/O queues for SSDs as they can easily handle up to tens of thousands of I/O operations concurrently without breaking a sweat. But if you have to use mechanical hard- drives, particularly the old and super slow 5.

I/O queue efficiently, touching the spinning plates as little as possible. And in this case, you will really want to use something like BFQ (or at least leave it at the default CFQ). You can check which I/O Scheduler you're running like this: 1. It includes de Mu. QSS scheduler instead of CFS and BFQ instead of CFQ, while also adding more tweaks for responsiveness like proper Qo. S over TCP to avoid TCP congestion.

In Arch Linux it's a simple thing to do: 1. Sy linux- zensudo grub- mkconfig - o /boot/grub/grub. For Ubuntu, you may want to refer to Liquorix's Install Page as it depends on your CPU, but most likely you will install on 6. Is GNOME 3 too slow? I always heard that GNOME and even KDE are too slow, you should just use XFCE (or LXQt, or MATE). And it always striked me as one of those things people just keep repeating until it becomes the official canon. As an engineer, I dislike thinking that way.

Defying the canon is more like what an engineer should do. GNOME 3. 2. 2 is an ever evolving environment and ecosystem. It's good looking by default, no need to tweak it too much. And it has several built- in conveniences such as GNOME Online Accounts, Tracker for indexing files and making them easily searchable, GNOME Photos that sync from Google Photos, and so on.

Every nicety we like about a system like mac. OS. Convenience is a trade- off of performance and responsiveness. So high- end machines will benefit from the convenience and old machines will suffer because of the extra .

The first thing you must install is htop and iotop. The first is good to see what processes running in the background may be eating up your CPU or RAM. The second is good to see what processes are bloating your I/O queues doing background file/network operations. What I found out in my system were 2 main offenders: Dropbox and Tracker. Dropbox is optional, but most people nowadays use it. Out of the box it is a hidious monster, one of the worst pieces of software you're obligated to live with.
