All three new models are dual G5s, from the low-end 1.8GHz models to the top-end 2.5Ghz, rolling out with 8X SuperDrives and the recently-redesigned motherboards and cases changes (which were slight, and not overly noteworthy). As usual, they run Photoshop really quickly.

Ace's Hardware has published an in-depth server review featuring a 4-way Opteron 848 server, 2-way Opteron 248, and 2-way 3.06 GHz Pentium 4 Xeon DP (1 MB L3). The benchmarks include a number of real-world Java application server benchmarks, Apache HTTP benchmarking, MySQL datamining, and more. The effect of NUMA-aware optimizations on scalability is also considered, as well as the performance differences associated with 64-bit (AMD64) binaries over legacy x86 binaries.

Benchmarking PHP with no BS


Benchmarking PHP with no BS 04/09/2004 03:58 PM
After I posted my XML benchmarks in February 2004, I was approached by Indu Britto to convert a discussion of the full benchmarks into an article for PHP Magazine. I kept on postponing him (correction, 2 Apr 2004: Indu is a her, apologies for the goof), but in a way, Prophet Mohammed helped me write the article. I'm not muslim, but the prophet's birthday is a public holiday in Malaysia. That gave me the breathing room to write the article.

I tried to make the article interesting by not focusing on the mechanics of the benchmark (yawn), but on useful results that everyone can use to improve their code. I was very pleased (and surprised - no one told me beforehand) to hear that the editors decided to feature it as the main article of the March 2004 issue.

Now that it has been published, i can announce that the source code of the benchmarking suite and results are available at http://ormestech.com/benchmark_suite/ . The results are static html pages to prevent enthusiatic testers from bringing our server to its knees. You should download the source code to try out all its functionality. The benchmarks are easily extensible also. You just need to add new benchmarking files and the benchmarking suite will auto-detect the files.

The nice thing about the benchmarks is that it measures relative performance between algorithms, so you can make meaningful conclusions across disparate hardware platforms. And if you need more clarification, you can read it (shameless plug) in PHP-Mag.


Going the whole hog: benchmarking MDB


Going the whole hog: benchmarking MDB 02/06/2003 11:53 AM
Well since I just benchmarked dbx, I decided to go the whole hog and benchmark MDB also. This gives us a good idea of the performance of all the modern database abstraction classes available for PHP:
        Average	 Overhead
MySQL	 1.14	  -
dbx      1.37     20% (index only)
ADODB	 1.45	  27%
dbx      1.53     34% (index/assoc/info)
PhpLib	 1.60	  40%
MDB      1.75	  54%
PEAR DB  2.87	 152% (fetchInto)
PEAR DB  3.15	 176% (fetchRow)
M'base	 2.52	 296% (numeric cols)
M'base	 4.77	 318% (assoc cols)

John's PHP Benchmarking Suite (ZIP)


John's PHP Benchmarking Suite (ZIP) 02/11/2004 12:26 PM
My benchmarking suite. Apart from XML, it also benchmarks string handling, looping (foreach vs for), output buffering, etc. And it's easily extensible too.

I wrote it when i was thinking about writing a book on optimizing PHP, and realized i would need a benchmarking suite to test various performance hypotheses. Its not OOP, but i think it demonstrates how far you can make procedural programming extensible in PHP.

The benchmarking engine scans sub-directories, and each sub-directory is treated as a test suite. A .php file in a sub-directory is one test. Every .php file in a sub-directory can be run stand-alone, and when running stand-alone debugging output is generated so you can verify the correctness of the code you are measuring.

To install, just unpack in a web server directory, and open up index.php from your web browser.

Requires PHP 4.3 or later.
