How to create System Image

Post date: November 17, 2008, 11:11 Category: System Views: 4106 Comments
Tutorial quote: Suppose you have a 40GB hard disk and a removable hard disk whose capacity is 60GB, and you want to backup all the files from the hard disk to the removable disk. With "dd", it is a very easy task. Again, suppose your hard disk's Unix device name is /dev/sda and the removable disk is /dev/sdb. The following command can copy all the content from /dev/sda to /dev/sdb:

High Performance MySQL

Post date: December 1, 2006, 04:12 Category: Optimizing Views: 6517 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.

Postfix performance tuning

Post date: May 21, 2005, 11:05 Category: Optimizing Views: 4090 Comments
Tutorial quote: Postfix is fast out of the box, but like other packages, you can usually tune it to work even faster. Furthermore, there are situations where Postfix may not perform as well as you expected, whether because of hardware or software limitations on the server system or other adverse conditions, such as a big influx of spam or undeliverable mail. This article shows you how to find and analyze the most common performance problems.

Tutorial quote: Mary, the daughter of a friend is in college: her Windows XP laptop constantly reboots and, we suspect, has a bad hard drive. The system will boot a live CD (Ubuntu 9.10 Karmic Koala Desktop), and data on the hard drive can be read. During boot, the live CD identifies disk errors and tries unsuccessfully to repair them.
