3 Reasons Why Your System Might Be Slow

Computer users expect their systems to work well at all times, but unfortunately this isn’t always the case. If your system becomes slow, there certainly is something you can do about it. This article will help you understand what’s happening on the system, whether it’s the computer in front of you or a system you’re accessing remotely.

When we say the system is slow we mean that it isn’t responding to our input in a reasonable time, or taking too long to complete a task. This can happen when there is *another* program using too many system resources, starving *your* program of resources, causing it to run slowly

There are three common ways in which this can happen, and all three of these scenarios can be equally crippling and put your system into a state where it seems to be frozen.

A program is monopolizing the cpu.
A program is using all of the cpu cycles, blocking access to the cpu to other programs. This may be intentional (programs that do heavy processing) or accidental (programs get stuck repeating something over and over).

You’re nearly out of physical memory.
You are either running too many programs, or programs that use too much memory. Your physical memory is almost entirely exhausted, and the running programs are using the harddisk as fallback memory, which is very slow.

A program is doing heavy I/O.
You may be copying a large file, for instance. The program that is doing the copying is requesting lots of data from the harddrive, but while it’s doing this the cpu is actually waiting for this data to be read from the harddrive, blocking access to other programs.

Leftovers: Ubuntu

  • Ubuntu-based Smartphones And Tablets Sound Good, On Paper, But...Do They Make Any Sense?
    As I previously stated in a recent article, I'm a huge fan of Ubuntu as a desktop operating system. It's friendly, reliable, consumes little resources and is largely virus-free.
  • Elementary OS 0.4 ‘Loki’ expected to be based on Ubuntu 16.04
    Elementary OS 0.4 ‘Loki’ coming soon, to be based on Ubuntu 16.04 and have plenty of new features
  • BQ Aquaris M10 Ubuntu Edition tablet - The heat is on
    Some investments are financial. Some are emotional. When it comes to Linux on tablets, my motives are mostly of the latter kind. I was super-excited to learn BQ was launching a tablet with Ubuntu, something that I have been waiting for a good solid three years now. We had the phone released last spring, and now there's a tablet. The cycle is almost complete. Now, as you know, I was only mildly pleased with the Ubuntu phone. It is a very neat product, but it is not yet as good as the competitors, across all shades of the usability spectrum. But this tablet promises a lot. Full HD, desktop-touch continuum, seamless usage model, and more. Let us have a look.
  • Kubuntu-16.04 — a review
    The kubuntu implementation of Plasma 5 seems to work quite well. It’s close to what I am seeing in other implementations. It includes the Libre Office software, rather than the KDE office suite. But most users will prefer that anyway. I’m not a big fan of the default menu. But the menu can easily be switched to one of the alternative forms. I’ve already done that, and am preferring the “launcher based on cascading popup menus”. If you are trying kubuntu, I suggest you experiment with the alternative formats to see which you prefer.
  • Ubuntu 16.04 LTS Review: Very Stable & Improved, Buggy Software Center, Though
    In almost all the occasions that I tested Ubuntu LTS releases, quite rightly so, they’ve always worked better than the non-LTS releases. And this Ubuntu 16.04 LTS, the 6th of such release is no exception. This one actually is even more impressive than the others because it has addressed some security related issues and even although not critical, subtle issues that I mentioned in the review. As far as the performance was concerned, Ubuntu 16.04 LTS was only largely outperformed by the memory usage where there is a large increase in memory usage. Other than that, those numbers look pretty good to me. That ‘.deb’ file issues with the Software Center is the only major concern that I can come up with. But I’m sure it’ll be fixed very soon.

Devuan Beta, Stumbling Tumbleweed, Ubuntu Too

Devuan Jessie beta released

dear Init Freedom Lovers, once again the Veteran Unix Admins salute you.
