Firevault startup time

Does enabling firevault slow down boot up or start up from the login screen?

I do not notice any startup slow down. Our household has a 2014 & 2015 MBP, the 2014 has FileVault enabled and the 2015 does not. The 2014 FileVault MBP boots just as fast as the non-FileVault MBP after login.

I find that since I enabled it, after entering my password on the login screen, a progress bar comes up. That didn't happen before. It used to just go straight to the home screen.

Yes, that's normal. It adds only a few secs or so to a non-FV login.

Yes, the decrypt happens after entering the login password. The time it takes depends on hardware. My MacBook Air or Retina MacBook with PCIe SSDs go through it quickly enough that it's not an issue. If you have a hard drive, it'll take longer. But really, how often do you do a full restart? It's worth the wait for data security.

I slightly mis-spoke. The whole startup process is about the same time, but in a different order. You should see the load bar either way, just in a different order.

2014 MBP with FileVault:
Press Start button
Almost instant Login screen
Enter password
Load bar displayed while FileVault decrypts and loads system

2015 MBP without FileVault:
Press Start button
Load bar displayed
Login screen
Enter password
Spin wheel displayed momentarily while loads system

It seems like about the same overall time to me.
