I think I found the problem: snapshots! I was building my new templates and had snapshots so I could undo a mistake without having to start over. For some reason Windows 10 1809 really doesn’t like snapshots. As long as there’s no snaps everytihng is fine. If I take a snap and reboot, the time it takes is noticebly longer.
ESXi 6.5 U1 seems to be the worst.
ESXi 6.7 seems better by comparison
ESXi 6.0 seems like it might not be affected (but this is on another environment)
I did a test by installing without having a snap and it was fast.
Rebooted right after and it was fast
Shutdown and took a snapshot (the only one) then powered on and noticeably slower.
Maybe there’s an advanced setting I can play with but again, this problem didn’t happen on Server 2019. ANy ideas?
My users take a bunch of snapshots as part of their tests so yes, this is going to be an issue for me
