Haven't touched it yet, I can do that this afternoon (gathering data this morning
on how re-upping the lock-hash-slots to 5099, and increasing the lock-memory,
affects things.)

Since we're on Windows Server 2008, the nbackup default would be 'ON', right? And
since we've got the cache-quota set now (default 30% of RAM), I guess the logic
would be that it ought to be safe enough to let nbackup allow the OS filesystem
cache to help it out, rather than brute-force it? Or is there some other logic to
messing with the setting?

I'm not sure why the behavior would have changed from 2.1.5 though, all else being
