The first time you launch an application on OS X, the OS does  
something called pre-binding. This is an attempt by the OS to speed  
up subsequent launches by optimising the mach-0 linker. OS X also  
uses smart caching to speed up the launch of apps that you have used  
recently or used a lot.

Other explanations have to do with Disk Fragmentation, Available  
(unwired) RAM, CPU speed differences between the machines you are  
testing on. Once you drop below a certain RAM threshold (I find it to  
be about 512MB) launching apps slows down exponentially.

The only way you can optimise launch speed is to try and trim your  
executable size. Loading all resources externally helps a lot (store  
you resources inside the app bundles resources file instead of  
dragging them into the project).
