Ahh seems like a few people do take the time to read my blog:) Peter Z Commented here on my common disk performance mistakes post. He makes some great arguments, and you may want to give it a read. While he does not agree with everything I say it is interesting to see his views. Remember different folks have different experiences and a lot of times there are multiple roads on the path the performance nirvana.
Let me start off saying I wholly admit that saying “everything” is a disk issue is a dramatic exaggeration. And i did not specifically say disk, I said “The problem is always an IO problem”, more on that later. I have run into my far share of issues outside of this sphere ( network, context switching, cpu ), but I still find disk performance to be by far the most common issue effecting systems I deal with. In my …

This article provides a comparison between the MyISAM and InnoDB storage engines for MySQL. InnoDB is commonly considered to perform worse than MyISAM, but this article aims to dispel this myth by describing the differences between these engines and what makes InnoDB a good fit for many database needs.
In addition, a look at when it is better to use MyISAM and a case study of the drupal.org site provide insight for determining which engine is best for a given situation.

Over the past several years whether I am working with a small company or a fortune 500 client I have seen lots of issues and mistakes made around the configuration, setup, and ongoing maintenance of disk on Unix and Linux Servers. This is not only an issue with MySQL shops, rather it can be an issue with all database setups whether it is Oracle, DB2, or Sybase. Neglecting the disk is setting yourself up for long term issues. These mistakes often force companies to throw more and more hardware at the problem… Lets look at some common mistakes around disk:
#1 The problem is always an IO problem, and remember spindles not capacity
In performance disk is everything. It makes you happy, it makes you sad. Learn to love it. Learn to hate it. Learn to understand it. Everything eventually comes back to disk. Take this example: Lets say you have a bad query that you fix with an index. Why …
