Slim Down and Speed Up Linux

Post date: December 17, 2007, 06:12 Category: Optimizing Views: 7147 Comments
Tutorial quote: While Linux is pretty efficient with a computer's resources out of the box, there are still ways you can make it run leaner and meaner on your desktop. Using a little bit of know-how, a willingness to run a few terminal commands and a mind for efficiency, you can get every last bit of power from your Linux box, or get more life from an older system. Read on for a roundup of ways to slim down and speed up Linux that any level of user can implement.

Speeding Up Perl Scripts With SpeedyCGI/PersistentPerl On Debian Etch

Post date: September 12, 2007, 22:09 Category: Optimizing Views: 3692 Comments
Tutorial quote: This tutorial shows how to install and use SpeedyCGI (also known as PersistentPerl) on a Debian Etch system. SpeedyCGI is a way to run Perl scripts persistently, which can make them run much more quickly. It keeps the Perl interpreter running, and during subsequent runs, this interpreter is used to handle new executions instead of starting a new Perl interpreter each time.

Installing The PHP-MemCache Module On CentOS 5.0

Post date: July 16, 2007, 23:07 Category: Optimizing Views: 6152 Comments
Tutorial quote: MemCached is a high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load. In this article I explain how you can very easily install it and make it avaible in PHP.

High Performance MySQL

Post date: December 1, 2006, 04:12 Category: Optimizing Views: 5711 Comments
Tutorial quote: The operating system your MySQL server runs on and the server's configuration can be just as important to your server's performance as the indexes, schema, or queries themselves. In this chapter, we will help you understand how to tune your server to improve performance, as opposed to tuning schema or queries. We'll be looking at changes to your hardware, operating system, and MySQL configuration to see what effects they have on overall performance.

We assume that you've already made efforts to boost the performance of your queries. If you haven't done that already, stop now and read Chapter 4 and Chapter 5 to get a handle on optimizing your queries and your application code. Only then should you worry about server settings. Hardware is often not the solution to MySQL performance problems. Poorly optimized queries can slow you down far more than not having the latest CPU or SCSI disk. To put this in perspective, one of the MySQL AB trainers even says that changing hardware might, in the best cases, give you a 10-fold performance increase. But tuning queries (and schemas) can often give you 1000-fold performance increase. Seriously.

Some topics covered in this chapter are platform-specific. The authors' knowledge of the various platforms on which MySQL runs is limited. In many cases, you'll need to consult your local documentation for various operating system tools and specifics.

We start with an overview of the factors that limit performance and then look more in depth at RAID, hardware, and operating system issues. The chapter finishes with a discussion of techniques you can use to locate, identify, and fix bottlenecks.

Optimizing DSPAM + MySQL 4.1

Post date: April 2, 2006, 22:04 Category: Optimizing Views: 3734 Comments
Tutorial quote: DSPAM is a scalable and open-source content-based spam filter designed for multi-user enterprise systems. It's great at filtering out spam but on busy mailservers the pruning of the MySQL databases takes way too long time ...

Configuring Apache for Maximum Performance

Post date: April 1, 2006, 03:04 Category: Optimizing Views: 4210 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.

Configuring Apache for Maximum Performance

Post date: February 12, 2006, 09:02 Category: Optimizing Views: 3721 Comments
Tutorial quote: Apache is an open-source HTTP server implementation. It is the most popular web server on the Internet; the December 2005 Web Server Survey conducted by Netcraft [1] shows that about 70% of the web sites on Internet are using Apache.

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 Linux systems. Of course, it is assumed that there is enough hardware resources - especially enough RAM that the server isn't swapping frequently. First two sections look into various Compile-Time and Run-Time configuration options. The Run-Time section assumes that Apache is compiled with prefork MPM. HTTP compression and caching is discussed next. Finally, using separate servers for serving static and dynamic contents is covered. Basic knowledge of compiling and configuring Apache and Linux are assumed.

Configuring Apache - Don't Succumb To The "Slashdot Effect"

Post date: January 31, 2006, 03:01 Category: Optimizing Views: 3770 Comments
Tutorial quote: Like many techno-geeks I host my LAMP website on a cheap ($150) computer and my broadband connection. I have also wondered what would happen if my site was linked on Slashdot or Digg. Specifically, would my setup be able to survive the "Slashdot Effect?" A Pentium 100mhz can easily saturate a T1's worth of bandwidth and my upload speed is capped (supposedly) at 384kbps, so the server should easily be able to handle that. My bandwidth will be saturated before the server is incapacitated, at least that's the idea.
