I think most people just want you to use the exact same configuration  
file on both systems and verify that both use the same pre-compiled  
options as well.  Probably the best thing to do is build from source  
on both linux and freebsd with the same options.  Make sure the  
defaults for each system are fair as well.  Then use the same config  
file or as close as possible on both operating systems.  Otherwise,  
you're not testing the same thing.   If you were testing against  
another architecture like say windows, then you would need to use the  
default worker type for windows.
