In a new post to his blog Alexey Zakhlestin talks about the "rebirth" of the XSLCache extension for PHP, this time as a PECL module.

XSLCache extension for PHP, originally developed by NYTimes started its second life in PECL's repository and I am proud to announce first PECL-release. The XSL Cache extension is a modification of PHP's standard XSL extension that caches the parsed XSL stylesheet representation between sessions for 2.5x boost in performance for sites that repeatedly apply the same transform.

It works with the normal XSL extension with some small differences around which classname to use and a change to the importStylesheet function.
