We’ve been trying to make Magento perform better – and one of the most simple things to do is have your php code cached. APC is a package that does this…
Since Ubuntu VM is of an ancient distribution (8.04LTS) I couldn’t do it the super easy Zend Framework way, but this blog got me through.
Down in the comments there is a helpful post about using wget and compiling it – worked like a charm! Then just move the apc.php file into your wordpress directory and bam, off you go!
Probably should secure that somehow…
