Why does OS X boot time Increase w/ Bootcamp/Parallels/Vmware?

Installed a fresh SL with my new Intel X25 M 160 GB SSD and I did boot camp and that slowed down the amazing 15 second boot time to 30 seconds. Downloaded the trial of both and Parallels and Vmware and it did the same thing. I then reinstalled SL and once again updated to the dreaded 10.6.4 and boot time increased again so then I left it alone and it went back to normal. I really need to use Windows on here for some applications but I don't understand why my OS X boot time increases with these programs and especially boot camp??? I'm starting to think no one else is experiencing this because they already had these programs on there computer and then updated to 10.6.4?

So what I want to know is...does SL index the boot cache or something after these programs? I am tempted to try again and leave it alone and maybe it will be fine.

There just has to be someone out there who is using Snow Leopard 10.6.4 and tried installing either boot camp, parallels, or vmware and watched their OS X boot time increase???

I did the following afterwards:

Reset PRAM
Repaired Disk Permissions
Used Onyx to clean out boot cache
Made sure the Mac OS X HD is selected as Startup disk
Rebooted a dozen times

Only thing I have not done was leave the OS alone so it can maybe index itself or something???

Thanks and hopefully someone can shed some insight on this for me
