I released the version 0.4 version of the plugin at
http://wordpress.org/extend/plugins/performance-testing/, which will
allow those who download the plugin to update when a new release comes
out. Overall, several issues have been worked out. However, there is
still one important issue to look at, which is some files aren't
completely finishing and then being removed I'm going to look at this
tonight and see where the issue is.
I want to add a few more features to it before the first stable
release, but I'm going to focus on them after the Google Summer of
Code. I hope to have the stable release out by the end of this year.
Next week, Sunday, I'm going to start on the WordPress PHP extension.
The goal of this second project is to write of the WordPress library
in a C++ WordPress PHP Extension. This will hopefully improve the
performance in several areas. XDebug can be used to test the
performance of the C++ version of the WordPress Library. Another goal
is to build the PHP extension to where it is easy to maintain and
improve upon by others.
The issue with writing a PHP extension based off of a PHP library, is
that it is a lot easier and quicker to write functionality in PHP than
it is in C++, because of the additional testing that is required. I
have talk to others who are willing to work on such a project, if
there was something that they could build upon or something already
available.
