Exposing Processor Features to Dynamic Languages

Intel® for its part invests countless hours and billions of transistors to add features in our silicon products which will speed up people's lives. If only they knew how to take advantage of it! Part of our job in dynamic languages is what I call "putting the cookies on the bottom shelf". Make this advanced technology easily consumable, and show you the value of it so you can be sure to use it.

The 0-Day Challenge: What is the Pulse of the Internet?

The core components of the Internet get updated constantly. Every time the source changes, the health and performance can change. A single source code change can fail to build, can break compatibility with existing code and can change the performance anywhere from a fraction of a percent up to 10% or more on major customer workloads. We're trying to read the pulse of our core components (Python,...

My Reality Moment. Why Did I Ever Agree to Do This?

When I first took this job of leading our scripting languages area, the Reality Moment struck when I had my first real look at the challenges of dynamic languages. For example, if you compare two strings in a program, we have some new instructions in the processor which can make these go very fast. But unfortunately, if you compare two strings in PHP, you first need to determine if the strings...

PHP - the right tool for the job?

Today there is a profusion of computer languages targeted at different activities. It's important to choose the right one. A lot of programmers love Python because it's so fast to implement stuff, but it can be a pain to use to create a simple website. PHP is the most popular choice for implementing active content in a website. And it's rather obvious once you dig into it. As you create your web...

HHVM and Haswell

There is no question that PHP is the most popular language in use today to implement server code on web pages. Something like 80% of web sites are implemented using it. The extremely popular site Facebook has implemented their own PHP interpreter called HHVM, and they are doing code development on it as an open source project. Because of its performance and its open source methodology, it is also...

PGO: Let It Go (PHP)

We can hope that companies like Intel® will come along with a faster processor. (And this does tend to happen every year). Or we can improve our compilers to produce better machine code. Or we can analyze our own code and change it to run more optimally. For PHP, we do all three: We partner with the processor architects to improve the way they execute PHP; we look for changes we can make to the...

High Performance PHP 7

On October 21, 2015, I was invited to give a technical talk at ZendCon, the largest gathering of the PHP community. A lot of excitement this year surrounds the release of PHP 7 which represents a massive performance improvement over previous versions. Here are a few notes from my talk. The promise was to offer a way for attendees of the talk to get even more performance out of PHP 7. We show you...
