memory usage

In a new post to his blog Ilia Alshanetsky takes a look at PHP's output buffering feature and some interesting things he found when testing some recent code (hint: it has to do with PHP's "interesting" management of the buffer).

While profiling our application I came across a a rather strange memory usage by the ob_start() function. We do use ob_start() quite a bit to defer output of data, which is a common thing in many applications.

Firefox’s single largest consumer of RAM, its JavaScript engine SpiderMonkey, is going on the mother of all diets. At any one time, SpiderMonkey’s memory footprint can be over 50% of Firefox’s total usage — the JavaScript on the ExtremeTech homepage, for example, uses no less than 115MB of memory — and slipstreaming SpiderMonkey is by far the best change that Mozilla can make to keep Firefox on the desktop svelte and competitive with Chrome and IE, and Firefox on Android less sluggish.

My previous post about using Silex and AppServer-in-PHP similarly to ExpressJS generate quite a bit of interest.

In the Hacker News thread there was a question about memory usage, and so I put the AppServer under siege.

Memory usage stayed constant at:

Version 1.1 is the latest release of Rubinius, a Ruby implementation based around a C++ and LLVM virtual machine but with the bytecode compiler and majority of the core written in Ruby itself.

It's often called a "Ruby in Ruby." We celebrated and explained the background to Rubinius' 1.0 release 4 months ago.

Paul Reinheimer has a reminder shown in his latest post about optimizing your scripts - don't forget the basics like unset.

Craig Buckler has added a new post to the SitePoint PHP blog today that looks at some of the PHP configuration options and how you can change them from two different places (besides the php.ini file).
