Do you have something copying files off of this machine, perhaps a tape
backup or something copy files across the network? I see this sort of
thing when copying files from server to server. The page faults occur
as the files are read from disk.Hi, I have a SQL Server 2000 with 14 different databases. I have been
monitoring it for some time, and it seems there is a high number of
page faults occurring. The number is constantly above 3000. The server

The Pages/sec counter is stabilised at a very low level (mostly it is
at 0). The SQL Server Cache hit ratio is mostly at 99%. The server is a
dedicated SQL Server.
So what could be causing the high amount of Page Faults?

jobs are running that copies files from the server.
The Page Faults are constantly over 3000 during the whole working day.
Maybe there's some fileshare that is accessed constantly by users (it's
a customer's server, and they said it was dedicated as a sql server,
but who knows...) ? Anyway, I will get back with any results.

faults. Go to the Processes tab on Task Manager, and rank the output by page
Faults or PF delta. It's common to have page faults in hundreds without any
performance issue. But if it's constantly around 3000, I'd conisder that hig
h
(just from the numbers I've seen on some of the busy servers in my
environments).
