Try to find which part of the boot procedure is slowing down the system so you know where to focus on.
You can use the following commands in Terminal:

Code: [Select]
systemd-analyze
and

Code: [Select]
systemd-analyze blame

Any other ideas.  I'm using an Logitech wireless integrated mouse/keyboard and a wireless headset although that is not usually turned on at start up.
Cheers Rob

If you are not using bluetooth I should disable the service during startup since it cost you some time.
Don't see really shocking issues here to be honest.
Maybe IPv6 slows it down. You can try to boot without your wireless enabled to see if it makes a difference too.
