Optimizing Desktop Performance, Part I

Post date: May 16, 2005, 23:05 Category: Optimizing Views: 3665 Comments
Tutorial quote: If you have complained about the speed of OpenOffice.org or Firefox or about the amount of time Linux takes to boot up, this set of optimizations should change your perception. Linux can boot up quickly, the word processor can spring open and the browser can fly. So, let's make these adjustments so your computer can fly.

Easy Automated Snapshot-Style Backups with Linux and Rsync

Post date: February 1, 2006, 00:02 Category: Software Views: 3007 Comments
Tutorial quote: This document describes a method for generating automatic rotating "snapshot"-style backups on a Unix-based system, with specific examples drawn from the author's GNU/Linux experience. Snapshot backups are a feature of some high-end industrial file servers; they create the illusion of multiple, full backups per day without the space or processing overhead. All of the snapshots are read-only, and are accessible directly by users as special system directories. It is often possible to store several hours, days, and even weeks' worth of snapshots with slightly more than 2x storage. This method, while not as space-efficient as some of the proprietary technologies (which, using special copy-on-write filesystems, can operate on slightly more than 1x storage), makes use of only standard file utilities and the common rsync program, which is installed by default on most Linux distributions. Properly configured, the method can also protect against hard disk failure, root compromises, or even back up a network of heterogeneous desktops automatically.

Optimizing Desktop Performance, Part II

Post date: May 24, 2005, 18:05 Category: Optimizing Views: 3349 Comments
Tutorial quote: As we discussed in last week's article, for most of its existence, people have distributed Linux as a workstation or a server rather than as a desktop. The default workstation that evolved has existed mostly for use by developers. So, when you install a Linux distribution with a graphical interface, it generally looks like what a developer might want. In addition, it performs similar to how many UNIX workstations work, which can seem slow.

In this article, we continue to look at the Linux desktop in a different light. Here, we think of it as a computer system with a fast interface that we can optimize for the knowledge worker and consumer.

Getting started with RHEL4's built-in LVM tools

Post date: June 3, 2005, 16:06 Category: System Views: 6038 Comments
Tutorial quote: Many Unix administrators I know (you know who you are), always used to smirk when I talked about Linux. They could always point to the fact that regardless of whatever I could say, they had journaling file systems, which they could manage using various Logical Volume Management (LVM) tools, and I couldn't touch that.

Well, not any more! Not only does Red Hat offer ext3 as their default file system, but they offer great management tools to boot. As we know, ext2 had a great lifespan, but it was not an enterprise-ready file system that could handle large disk partitions, fast recovery from systems crashes, or large amounts of files. Journaling file systems give you the ability to recover almost instantly from a crash, as you do not need to run fsck after a restart. Similar to how databases recover from crashes, a journaling file system tracks changes to file system metadata and pretty much guarantees that either all or no updates have completed. Of course, these file systems also need elaborate tools to help better configure and manage them accordingly.

The IPv6 Internet: Connect Today with Linux

Post date: April 13, 2005, 03:04 Category: Network Views: 3147 Comments
Tutorial quote: IPv6 is a key technology and a long-term solution to build scalable, reliable, manageable, secure, and high-performance IP networks. In this article, I demonstrated how to configure a Linux machine running Fedora Core 1 to support IPv6 and connect it to the IPv6 Internet using the Freenet6 service.

Building a Linux Cluster, Part 1

Post date: April 18, 2005, 03:04 Category: Network Views: 2366 Comments
Tutorial quote: Linux clusters have escaped. As the general popularity of the Linux operating system increases, more complex solutions built with it are becoming increasingly common in the "traditional" (more conservative) IT world. Linux computer clusters, whose provenance was originally universities and research institutions such as the U.S. National Laboratories, are showing up in increasing numbers as high-performance computing solutions within such areas as oil and gas exploration, computer-aided engineering, visualization, and software development. Linux clusters providing highly-available web, mail, and other infrastructure services are also increasingly common. If past computing history is any indicator of future trends, widespread use of Linux clusters in the mainstream IT world cannot be far behind.

Managing Filesystems : fstab

Post date: April 15, 2005, 23:04 Category: System Views: 6551 Comments
Tutorial quote: Understanding how the BSD filesystem manages disk space is critical to successfully managing a BSD server or workstation. However, this topic is generally overlooked since it is rarely used outside of installation and upgrades. It is also a very simple topic and most people assume you understand how it all works.

This article gives a quick synopsis on filesystem layout and tries to briefly explain how to understand /etc/fstab. The fstab(5) man pages, while good, do little to teach the basics to new sysadmins.

Benchmarking Filesystems

Post date: April 12, 2005, 07:04 Category: Benchmarks Views: 2918 Comments
Tutorial quote: I recently purchased a Western Digital 250GB/8M/7200RPM drive and wondered which journaling file system I should use. I currently use ext2 on my other, smaller hard drives. Upon reboot or unclean shutdown, e2fsck takes a while on drives only 40 and 60 gigabytes. Therefore I knew using a journaling file system would be my best bet. The question is: which is the best? In order to determine this I used common operations that Linux users may perform on a regular basis instead of using benchmark tools such as Bonnie or Iozone. I wanted a "real life" benchmark analysis. A quick analogy: Just because the Ethernet-Over-Power-Lines may advertise 10mbps (1.25MB/s), in real world tests, peak speed is only 5mbps (625KB/s). This is why I chose to run my own tests versus using hard drive benchmarking tools.

BackupPC Installation And Configuration

Post date: June 19, 2006, 15:06 Category: Software Views: 3107 Comments
Tutorial quote: BackupPC is a high-performance, enterprise-grade system for backing up Linux and WinXX PCs and laptops to a server's disk. BackupPC is highly configurable and easy to install and maintain.

Benchmarking BSD and Linux

Post date: June 18, 2005, 22:06 Category: Benchmarks Views: 3621 Comments
Tutorial quote: These benchmarks are the result of my scalable network programming research. My interest in this area is to see how scalable and fast network applications can be on standard PC hardware.

I have done most of my research on Linux 2.4, 2.5 and 2.6 kernels using a home-grown distribution I affectionately call "Leanux". I have experimented with several APIs and methods to try and get the most scalability and performance out of a web server. The ultimate goal, however, is to demonstrate scalability by surviving a Slashdotting.
