You're Doing It Wrong
For a recent edition of the Swiss Computerworld Magazine we listed our Top 10 Performance Problems as we have seen them over the years when working with our clients. I hope this list is enlightening – and I’ve included follow-up links to the blogs to help better understand how to solve these problems: #1: Too Many Database Calls The problem we see the most are too many database query per request/transaction. There are 3 specific phenomena to witness More data is requested is than actually required in the context of the current transaction, e.g.: requesting all account information instead of those that we need to display on the current screen.The same data is requested multiple times.

Cowboy Programming » Mature Optimization This article originally appeared in the "Inner Product" column in Game Developer Magazine, January 2006 Last month I described an optimization that needs to be done early on in a project, if it is to be done at all. This month I expand on the theme of early optimizations, and present a few examples of what I call "Mature Optimization". Every year a fresh crop of young programmers enters the games industry with the wisdom of books and lectures swirling around their heads. One pearl of wisdom is drilled deep into their tender programming muscles; the pearl sometimes known as "Hoare's Dictum": "Premature optimization is the root of all evil" - C.A.R.
