Considerations for the system architect: Performance

Post date: April 20, 2005, 10:04 Category: Miscellaneous Views: 2868 Comments
Tutorial quote: For many developers and engineers, performance is often an afterthought. But when a product functions as designed and has proven stability and the right feature mix, success in the marketplace often depends upon performance. Architectural decisions define the ultimate feasible performance of any product. In this article, learn how performance-monitoring technology initially developed for mainframes can help you improve your own code's performance.

Rolling your own Debian packages (part 1)

Post date: January 21, 2006, 06:01 Category: Software Views: 2745 Comments
Tutorial quote: This two-part article explains how to make a Debian package of simple piece of software, presumably something you have written yourself. Although building a new package is more complex than rebuilding one or having one generated, the idea is that it is actually surprisingly simple to create basic Debian packages. In fact, if you can make software install into a temporary installation tree, you're already 90% done! This text provides a quick alternative to the more comprehensive Debian New Maintainers' Guide. Only knowledge of Makefiles and the basic Debian package tools is assumed.

The first part of this article will continue with some preliminary information about Debian packages. In the second part we walk through a concrete packaging example.

Choosing an I/O Scheduler for Red Hat Enterprise Linux 4

Post date: July 18, 2005, 22:07 Category: Benchmarks Views: 7444 Comments
Tutorial quote: The Linux kernel, the core of the operating system, is responsible for controlling disk access by using kernel I/O scheduling. Red Hat Enterprise Linux 3 with a 2.4 kernel base uses a single, robust, general purpose I/O elevator. The 2.4 I/O scheduler has a reasonable number of tuning options by controlling the amount of time a request remains in an I/O queue before being serviced using the elvtune command. While Red Hat Enterprise Linux 3 offers most workloads excellent performance, it does not always provide the best I/O characteristics for the wide range of applications in use by Linux users these days. The I/O schedulers provided in Red Hat Enterprise Linux 4, embedded in the 2.6 kernel, have advanced the I/O capabilities of Linux significantly. With Red Hat Enterprise Linux 4, applications can now optimize the kernel I/O at boot time, by selecting one of four different I/O schedulers.

Performance Tools for Optimizing Linux: Process-Specific CPU

Post date: June 1, 2005, 07:06 Category: Optimizing Views: 3152 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.
