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...

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...

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...

Making the Dead Rise, and Other Impossible Tasks

My current job is to lead our company's work on dynamic server languages, such as performance optimization and feature enabling. Besides PHP and HHVM, we want to improve Python. There is a huge amount of Python code in use out there, for example running OpenStack, Swift, DropBox and many others. What I didn't realize when I took the job was that much of this use is in a "dead" language.

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,...
