Using MySQL to benchmark OS performance

Post date: April 12, 2005, 07:04 Category: Benchmarks Views: 3509 Comments
Tutorial quote: It seems to be an exciting time for *nix operating systems, with a number of them recently releasing new versions that bring the addition of expanded features and claims of improved performance. If you're using GNU/Linux, OpenBSD, NetBSD, FreeBSD, or Solaris as a database server, you've probably recently considered an upgrade or switch to another OS in that list due to marketing hype and hearsay. This article will show you how to benchmark operating system performance using MySQL on these OSes so you can find out for yourself if you're missing out. While this may not necessarily be indicative of overall system performance or overall database application performance, it will tell you specifically how well MySQL performs on your platform.

The following operating systems were used for the comparison testing:
- FreeBSD 4.11
- FreeBSD 5.3
- NetBSD 2.0
- Linux 2.6
- Linux 2.4
- Solaris 10 x86 (build 69)
- OpenBSD 3.6

Comparing MySQL performance

Post date: April 12, 2005, 07:04 Category: Benchmarks Views: 3427 Comments
Tutorial quote: With the introduction of the 2.6 Linux kernel, FreeBSD-5-STABLE, Solaris 10, and now NetBSD 2.0, you might be wondering which of them offers superior database performance. In my previous article, I discussed the tools I chose to test these venerable operating systems and the methodology by which they were tested. The result is this MySQL performance comparison between OpenBSD 3.6; NetBSD 2.0; FreeBSD 5.3 and 4.10; Solaris Express (build 69); and Linux 2.4 and 2.6 (Gentoo-based). Read on for the results.

Performance Tools for Optimizing Linux: Process-Specific CPU

Post date: June 1, 2005, 07:06 Category: Optimizing Views: 3172 Comments
Tutorial quote: The tools to analyze the performance of applications are varied and have existed in one form or another since the early days of UNIX. It is critical to understand how an application is interacting with the operating system, CPU, and memory system to understand its performance. This chapter will help you understand where the bottleneck in your system is occuring, and how to fix it.

Configuring Apache for Maximum Performance

Post date: April 1, 2006, 03:04 Category: Optimizing Views: 4333 Comments
Tutorial quote: Apache server performance can be improved by adding additional hardware resources such as RAM, faster CPU etc. But, most of the time, the same result can be achieved by custom configuration of the server. This article looks into getting maximum performance out of Apache with the existing hardware resources, specifically on the Linux systems.

Benchmarking Maildir Delivery on Linux Filesystems

Post date: April 12, 2005, 07:04 Category: Benchmarks Views: 3029 Comments
Tutorial quote: The goal of this set of benchmarks is to determine which of the leading Linux filesystems (ext2, ext3, ReiserFS, and XFS) offer the best performance when used for accepting maildir deliveries. The resulting system should be a good balance of delivery and retrieval performance under potentially high concurrent filesystem load.

Optimizing Desktop Performance, Part III

Post date: May 31, 2005, 14:05 Category: Optimizing Views: 4322 Comments
Tutorial quote: For desktop and laptop users who want a fast-booting operating system, getting rid of services you do not need can appear to improve performance. Obviously, if you are new to Linux, though, you probably do not know which processes you can get rid of safely nor how to stop them and keep them from restarting at boot time.

Hacking OpenSUSE

Post date: December 3, 2005, 17:12 Category: System Views: 6789 Comments
Tutorial quote: There's more to SUSE Linux than simply installing it and going to work. To get the most from the operating system, you'll probably want to do some post-install fine tuning. This article by Jem Matzan explains how to: add download sources to YaST; install the Mozilla Thunderbird email client; add support for Java, Flash, Acrobat, Windows Media, MP3s, and RealMedia; play DVDs -- and more. It serves as a useful supplement to Steven J. Rosen's excellent how-to, "Installing SUSE Linux 10 on a Laptop," recently published here on DesktopLinux.com. Enjoy . . . !
