Paul Jones has taken a look at some performance statistics that Rasmus Lerdorf shared in a recent presentation from some of his tests.

As many of you know, I maintain a series of web framework benchmarks. The project codebase is here and the most recent report is here.

It was with some interest, then, that I viewed Rasmus Lerdorf’s slides on the subject of performance benchmarking.

On the ThinkPHP blog today, Stephanie Ehrling has posted about a method for PHP to take in the output of the Nike+ equipment and put it into a usable form.

Nike+ is a feature for the iPod nano which allows to measure time, distance and speed of runnings with a small sensor in running shoes that sends data to a transmitter on the iPod.

Those data are sent to a users Nike+ account by iTunes whenever the iPod is synchronized. On the Nike+ website there is a report of runnings, the average speed, total kilometers run etc.

The users can also compete with each other in virtual competitions and define goals to run more often, faster or a longer distance.

The Nike+ website displays the data graphically with Adobe Flash.

At DrupalCon Sunnyvale 2007, Rasmus Lerdorf chided Drupal on spending over half of its request time on just the bootstrap process.

As a GHOP Task , Cornil did a performance analysis of Drupal and found its two largest performance drains were the bootstrap process and the theming layer.

Quite simply, Drupal spends too much time including code.

Lukas Smith has posted the second and third parts of his talk with Rasmus Lerdorf - a look at MaxClients and HTTP headers.

Lukas Smith got a chance to catch up with Rasmus Lerdorf (and others in #php.pecl) and "talk shop" about topics including handling large libraries and maxclients settings.
