Some more plane hacking...

I did a bit of playing around with Smarty on the plane today. Basically I wrote a small C extension that creates the base Smarty class and initializes many of the variables. Then I extended that base Smarty class from user space with the existing user-space Smarty class stuff. The result was a 25% speedup in my limited ab tests. There is still a bunch of stuff in userspace that could easily be moved into the extension and thus provide more of a speedup. I also had a look at the pear DB class, although I didn't start writing any code for that one. I think Stig mentioned he was planning on pulling some of that into a PHP extension. But looking around in Pear there are a number of classes that could benefit greatly from a bit of help from a C extension. What is the overall feeling here about converting some of this stuff to C? -Rasmus
