Can you explain how you have your disks setup, raid level, location of logs,

Thats not the telling information typically.
Number of users per server, number and speed of disks for the DB, IOPs
per user, pefmon counter data, etc...

Hi Everyone,

I'm getting strange performance issues when on occasion (happens more
often
than not) when someone opens a shared calendar (usually one a user has not
used in a while) I am seeing a high Avg. Disk Queue Length count in
perfmon
(7-8). When the calendar is open, the count drops to around <1 again. This
is
quite consistant. I am also seeing RPC latency creeping up while this is
going on. While this is happening, users find that access to mailboxes etc
is
very slow. Does anyone have any idea on what this could be? I am also
getting
(but only on occasion) quite a lot of these Events: 8206, 8264, 8230 -
again,
issues with calendars.

Kind Regards,

Daran Clarke.
