Ubuntu 15.04 Provides Openstack Kilo Preinstalled for Easier Deployments on ONP Servers

The folks here at Intel see me as a bit of an Ubuntu fanboy.  For the most part, I spend a lot of time in the lab working on the ONP Server using CentOS.

Core Challenge In Speeding Up Python, PHP, HHVM, Node.js...

A traditional compiler translates a high-level computer program into machine code for the CPU you want to run it on. An interpreted language translates a high-level language into the machine code for some imaginary CPU. For historical reasons, this imaginary CPU is called a "virtual machine" and its instructions are called "byte code." One advantage of this approach is development speed: creating...

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...

Slides from ToorCon 17 talk on OpenSSL Performance

I've sent the slides from my talk on Improving OpenSSL Performance to the ToorCon staff for distribution, but I am also making them available for download here in PDF format. I chose PDF since many of the slides have extensive notes which go into much greater detail that the slides could, and in many cases even cover detail that I could not put into the 50-minute session on Saturday.

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...
