New performance wiki page
I’ve created a new wiki page with the aim of providing some background to factors which affect web stack performance and where to look for tweaks and alternatives.
Hopefully this will become a place where explanations of performance issues can be keep up to date, and used as reference when advising on potential improvements.
It should also provide a valuable resource for people to use to find ways to improve the performance of their own web stack.
Ideally it will concentrate on the platform rather than the Magento application itself as those concerns would be better catalogued elsewhere.
Please add your own ideas and experiences!

does anyone have any instructions on utilizing XCache or APC? For example, do I have to go in and modify all the magento files to use apc_compile_file() ? Or should just installing one of these opcode caches yield a performance gain?

APC (and I assume also XCache) are configured via your php.ini file. See http://uk3.php.net/manual/en/apc.configuration.php for the configuration options

Right, but after proper configuration, no modifications to the source files are needed to take advantage of the opcode caching right?
