Hello Danny,
The iLok wrapper does take a small number of seconds to to start before it launches Hauptwerk itself, during which time it would be validating that the application hasn't been tampered with, and that a relevant licence is present. I know of no way to make it quicker, I'm afraid (possibly apart from having a faster CPU, but I don't know for certain how much the CPU is the bottleneck, or exactly what the iLok system does internally during the process). I think it's just something that has to be lived with.
