There are dozens of paramaters (MySQL configuration, Apache  
configuration, opcode cache, MySQL cache, hardware, single-server vs  
multi-server setup, Drupal version, Drupal modules installed, Drupal  
settings, etc.)  What we really need is a script or tool that allows  
us to benchmark a particular setup.  The script/tool should take an  
input file with one or more navigation patterns or scenario's to  
simulate/benchmark.  We could use the same script to evaluate the  
performance impact of certain code changes.  Then, with the script/ 
tool we can benchmark and tune existing configurations and document  
our knowledge in a document.

In addition to such tool, we need tools to profile your site while  
being benchmarks.  Some profiling can be done by using certain Drupal  
modules/patches (eg. like the one I made to profile the cache  
behavior).  For other things, you might need other tools.
