Optimizing Linux for slow computers

This is a link to an article titled, “Optimizing Linux for slow computers.” Note that this article links to this more thorough resource on

Here are a couple of paragraphs from it:

When tuning a server, you'll really want to tweak for performance and high throughput. That's where most Linux configurations really shine over the competition: they come better tuned to get the most out of server configurations.

Java performance tuning: putting timers in code to benchmark performance

With a programming language/environment such as Java the performance of our Java code may be a concern. I often use an old-fashioned "quick-and-dirty" way to measure the performance of Java code, and I'll share that method in this brief article.

An old-fashioned manual method

I must confess, the method I use is as old-fashioned as they come. Generally it requires three steps:

Java profiling with JRat

Writing software is a funny thing. You do something one day and you think it's really cool, then come back another day and go "WTF was I thinking?", so you tear it apart and rewrite it.

Today I ran the JRat Java profiler (Runtime Analysis Toolkit) on some code I wrote about 10 days ago, and it showed that I was looking for a pixel 10,000,000+ times on a 1024x768 resolution image.

Java performance-related URLs

Just cleaning off an old PC that I used to use, and I find these URLs that some of our developers put together for an old "Java Performance Tuning" seminar:

Mon, Sep. 27, 2004 (Presentations at the Borland Conference, aka, Borcon 2004)

I'm finally getting back into the swing of things after being a presenter at the Borland Conference. To that end I'm making my papers and presentations available online at the following URLs. I think the titles of the papers are self-explanatory, so I'll just list them here.

Tue, July 6, 2004 (Speaking at BorCon 2004)

Over the weekend I saw that I'm on Borland's speaking schedule for their annual conference, BorCon 2004. I guess I better get to work on my presentations. :) Actually, I'm ready to go. I'm set to give one talk on Java Performance Tuning and another on Function Point technology. Giddyup.

I haven't frequented it before, but the Java & Internet Glossary at mindprod looks pretty good.
