First-Logon Times Are Unacceptable in Windows 10

Question

So far, we have found several issues with Windows 10 Enterprise, but our biggest issue -- by far -- is with the time it takes to logon a new user for the first time.  This was also an issue in Windows 8.1 and is also the reason we largely skipped Windows
8.1 where I work.
The time it takes for a user's first logon is too long, even when we disable the "Show first sign-in animation" setting.  I work at a large community college where employees and students frequently bounce from one computer
to another in the computer labs, often never using the same computer twice.  They login using their domain credentials.
With new 7200 RPM hard drives and relatively new computers, it takes approximately 160 seconds for a user to logon the first time.  With a new SSD, it takes approximately 50 seconds for a user to logon the first time.  These times are unacceptable
to us and is a deal breaker for Windows 10 deployment.  The largest part of the logon time is spent at the "Preparing Windows" phase of the first-time logon process.  This issue is serious enough for us that we would consider skipping Windows
10 and sticking with Windows 7 if it is not drastically alleviated.  Even Windows 7 first logons were not great, but we simply cannot accept how they are in Windows 10.

I have not noticed slow turn around with either Linux or Windows servers
so the client is step 1, then the server are looked at for policies that bottleneck
