I wrote about web page loading performance a while ago, when I linked to Dave Hyatt’s most excellent explanation of the issues involved with testing page load speed. In fact the Safari browser blog endorses Aaron Hopkins article and mentions how to measure page loading times in Safari using the debug menu.

On the Mozillia front, the Tamper Data extension generates some amazing graphs of when elements on a page load and how long it takes.

On the topic of sending less data, the Yahoo! User Interface Blog weighs in on page waits with a discussion of javascript minimization versus compression. They also briefly cover the YUI decision to serve components a la carte, rather than in an aggregated file.

Cal Henderson of Flickr also takes up this topic in serving JavaScript fast. He goes into more depth about the issue of a la carte external objects versus aggregated external objects as well as covering compression and caching issues with examples in PHP.

From the PHP perspective, Michael J. Radwin and Rasmus Lerdorf have covered web application performance issues in conference talks.

Are your web pages cacheable or not?

On the home front, this is my first post on this blog since I’ve installed wp-cache2 and upgraded to eAccelerator 0.9.5. And my first post since my fishing vacation, too

PHP Java C# Perl

PHP seems to be holding steady, or slightly declining. But, Java is waning, as I discussed in Why isn’t PHP the natural successor to Java?. C# seems to be steady and slightly increasing, while Perl is steady and slightly decreasing. So where are those Java programmers going if not PHP? Are they going to Ruby and Ruby on Rails?

Java Ruby Ruby on Rails

It looks like Ruby and Ruby on Rails are tiny fish in Java’s pond. Perhaps those Java developers are going to C# or one of Microsoft’s unsearchable variants. It would be interesting to see the MSN search trends. However, there is one area where Ruby on Rails seems to be doing well:

Struts Ruby on Rails framework

It used to be that most of the PHP frameworks were cloning Struts. Now they clone Rails. There is an increasing interest in frameworks.

There are countries where PHP is more popular. Here is the PHP vs. Java chart for the Netherlands. Right at the end, PHP beats out Java. Search, Derick. Search.

PHP Java

One last Trend. What is trendier that Ajax these days? Certainly not JavaScript.

Javascript AJAX

Notice how Javascript searches are declining while Ajax is ascending. Strangely I would have thought that the interest in AJAX would have created an increase in Javascript searches. It doesn’t look like the total search volume of the two terms together is increasing that much. Looking at the news volume graph is striking. The AJAX press release machine is in full gear. So is AJAX the thing that everyone is talking about, but nobody is doing? Can you say Web 2.0 bubble?

Please use the AJAX enabled comment form below to tell me how wrong I am.

Their server is getting crushed right now, intermittently not responding and running out of MySQL connections. The javascript crashed my browser a couple times. Still, I was intrigued by the combination of Ajax and PHP and I liked the interface. Definitely one to bookmark for later. (I’d like to track down that crasher when I get more time.)

What is the state of Ajax games? of PHP games? Are there other PHP/Ajax games that I should bookmark?
