Can you use static ip address in your network? The dhcp client did eat a lot of time here, too. 9 sec boot here without cryptsetup and static ip. Server needs 20 sec without ssd, 15 sec for dhcpcd, mysql and php-fpm
I do not believe that would help, because often I start up in areas without a network. Perhaps there is a way to get Network Manager to start after

NetworkManager works fine with roaming and can be configured to use a static IP on some networks but not others. I don't see what you have to gain by removing it from the regular boot process... just make sure you're not letting stuff block on it.
This is with NetworkManager enabled on a wireless network with a Samsung 840 EVO (it varies from ~2-3s for kernel + userspace):
Startup finished in 3.070s (firmware) + 60ms (loader) + 1.655s (kernel) + 676ms (userspace)
160ms NetworkManager.service
AFAIK it doesn't count the time needed to connect over DHCP... it's often not connected by the time I have a browser and a few terminals open in i3 since it takes 10 seconds.
Not that boot time should matter to anyone, since kernel upgrades aren't every day and there's not much reason to reboot otherwise :P.
So something seems to be wrong here. Startup finished in 4.637s (firmware) + 131ms (loader) + 2.790s (kernel) + 20.066s (userspace) = 27.626s
12s NetworkManager.service
What sort of things should I check for? Is there an /etc config file I can play with?
Use an efistub loader like gummiboot if you're not already, use lz4 compression for the kernel, disable staggered spin-up, use a single unsplit root partition and avoid remounting it, etc. I'm sure these things are all on the wiki somewhere, because I remember writing some of it. There's not really any magic to speed up starting a large number of services, if that's what you're doing. All I have enabled is chrony/pdnsd/NetworkManager and they don't block the boot process. I just use agetty to start up i3. I assume you've got something on the critical path depending on NetworkManager like a Type=idle service.
