Twig extension

London, UK Monday, November 21st 2011, 09:20 GMT

A while ago, Fabien asked me to have a look at porting one of Twig's slowest methods, TwigTemplate::getAttribute(), into a PHP extension.

It is a complex method that does a lot of different checks and look-ups.

Once upon a time, browser benchmarks were actually important -- but then Chrome came along.

Here are the slides from my PHPBenelux 2011 talk about benchmarking. This presentation includes updates to previous benchmarks; the graph is on slide 40.

The benchmarking project has moved from Google Code to Github at https://github.com/pmjones/php-framework-benchmarks.

LinuxDevices: "Phoronix has published the results of benchmarks performed on 26 Linux kernels dating back five years, from Linux 2.6.12 to a pre-release version of the upcoming Linux 2.6.37.

Despite the addition of numerous features over the years, the results show remarkable consistency."

Phoronix: "Over the next few weeks there are a number of new Phoronix benchmarks to be published concerning the performance of Mesa 7.9 for both the Mesa classic and Gallium3D drivers from the different GPU vendors."

The HTC Desire HD has been benchmarked and it's much faster than a Nexus One running Android 2.2 Froyo. And, the ROM has been ported to the HTC HD2!

Metadata performance is perhaps the most neglected facet of storage performance. In previous articles we've looked into how best to improve metadata performance without too much luck.

Could that be a function of the benchmark? Hmmm...

Phoronix: "To see how the performance difference is on the Intel side between the kernel mode-setting and user-space mode-setting implementations we ran a set of benchmarks on this side as well using Ubuntu 10.04."

Phoronix: "Last month we published benchmarks of EXT4 comparing this file-system's performance when it was first marked stable in the mainline kernel and then where it is at now in the Linux kernel while testing every major release in between."

The nouveau project has done it! Finally, an open source 3D driver for NVIDIA video cards has arrived and will ship with Fedora 13. Let's take a look (including a few benchmarks).
