Significante lag when starting up and presented with the login screen. Once I'm logged in everything is great.
This just started happening within this last week.
I've not added any software and only ran updates yesterday.
All help is appreciated.

Would you please specify what do you mean by "significant lag"? Please describe the issue with more details
Please take each of the following steps that you haven't already tried. Test after each one. Back up all data before making any changes.
1. Set the default startup disk.
2. Disconnect all wired peripherals except those needed to start up. If there's no change, reconnect them
3. Reset the System Management Controller.
4. Reset the PRAM.
I've done all of what you suggested. I am still having the problem, but now I discovered it only lags when I connect it to my Thunderbolt monitor. That seems to be where the problem is.
I have a MacBook Pro (Retina, 15-inch, mid 2014)
Could it be a monitor setting?
Thank you for the help.
Are any other peripherals connected to the display? If so, disconnect them and test. Otherwise, how long is the delay?
Fixed.
It was my Wacom tablet. I disconnected and everything was good. I then updated the drivers and problem solved.
Thank you.
