During the past week, I've been looking at different strategies for autoloading in Zend Framework. I've suspected for some time that our class loading strategy might be one source of performance degradation, and wanted to research some different approaches, and compare performance.

In this post, I'll outline the approaches I've tried, the benchmarking stategy I applied, and the results of benchmarking each approach.

My good friend, Rob, hosts my site for me, in return for helping with server maintenance. After being on Gentoo for the past three years, though, we decided it was time to switch to something a little easier to maintain, so last night we wiped the system partitions and installed Ubuntu server.

I'll say this: the setup is much faster! However, we had a few gotchas that surprised us -- it didn't setup our RAID array out-of-the-box, which led to a good hour of frustration as we tried to verify that the install wouldn't wipe it, and then to verify that we could re-assemble it. (We succeeded.) Additionally, we second-guessed a few things we shouldn't have, which led to needing to back out and reconfigure. But what was over a 12 hour install with Gentoo we accomplished in a matter of a few hours with Ubuntu server -- so it was a huge success that way.

Unfortunately, our mysqldump of all databases... wasn't, a fact we discovered only after importing it into the new system. I ended up losing my blog database and PEAR channel database. Fortunately, the PEAR channel has not changed at all in the past year, so we had an old backup that worked, and I had a snapshot of my blog database from three weeks ago I was able to use. As a result, there are a few missing entries, but for the most part, all works. If you commented on one of those missing entries, my apologies.

Now that the install is done, I'm also finalizing some design changes to my blog -- it's time to leave the black and white for more colorful grounds. Look for a revamp in the coming weeks!

2007 was a busy year, both personally and professionally. I won't go into the personal too much, because, well, it's personal, and some of the details are simply inappropriate for blogging material.

Here's the short version:

• One trip to Belgium and The Netherlands.
• Two trips to Israel.
• Two trips to Atlanta, GA (not counting the return trip from Europe, when I was stranded for a day due to storms in the Northeast).
• Three different user groups attended, with three presentations.
• One major Zend Framework release
• One PEAR release.
• One podcast.
• One webinar.
• One book published.
• One conference attended.

What follows is my month-by-month breakdown:

Over the past few evenings, I've refactored File_Fortune to have it implement Iterator, Countable, and ArrayAccess -- basically allowing it to act like an array for most intents and purposes. As a result, I've eliminated the need for the File_Fortune_Writer package, and greatly simplified the usage.

(Note: sure, File_Fortune may not be that big of a deal, but over 1000 downloads in the past two years indicates somebody is using it. Plus, it powers the random quotes on the family website. )

As some examples:

All-in-all, it's a much better interface. Lesson learned: when porting code from other languages, it pays to take some time and determine if there might be a better API in your own.

In upcoming releases, I hope to modify the backend to use PHP's Streams API instead of direct file access, and also to allow providing a list of fortune files explicitly. After that, I should be ready for the initial stable release.

Update (2007-07-10): fixed parse error in examples
