Awareness of Windows file IO throttling for exclusive files

[awitter]

Hello, I was wondering if anyone knows anything about Windows throttling the file IO when the database file has been exclusively opened. I received a question about that from a client, have searched for any information, but got out blank. This is not about network, vpn or hyper-v, but bare bone windows and disk.

Opening a file for exclusive access would have no impact at all on the IOs performed afterwards (no throttling). It is purely a locking mechanism to prevent other processes from accessing the file at the same time.

yes, that was my idea exactly.
