SnTT - How To Determine When You Need Another Mail.Box05/08/2008 06:44:27 PM
You have two mail.box files on your Domino server and you are wondering if you need another one. Is there a way to tell if your Domino server is need of a third mail.box?
You need to look at two Mail Statistics, Mail.Mailbox.Accesses and Mail.Mailbox.AccessConflicts. What are the meanings of these two stats?
From the Redpaper, Domino 7 Performance Tuning: Best Practices to Get the Most Out of Your Domino Infrastructure:
Mail.Mailbox.Accesses is the total number of times that threads accessed any mailbox on the server.
Mail.Mailbox.AccessConflicts is the he number of times that a thread attempting to access a mailbox had to wait because the number of concurrent threads exceeded the number of mailboxes configured. For example, if there are three mailboxes configured, and there are four concurrent accesses, the conflict count would be incremented. If the number of access conflicts consistently exceeds two percent of the value of Mail.Mailbox.Accesses, consider creating an additional mailbox.
To get these stats, go to the Server Console and type:
Sh stat mail
Then, with the numbers in hand, make this calculation:
(Mail.Mailbox.AccessConflicts / Mail.Mailbox.Accesses) x 100 = X.
If the value of X is greater than two, consistently, you need another mail.box.
But remember, you have to have two or more mail.box' on your Domino server in order to capture these statistics.

This post is GOLD. I've been looking for good examples of multiple stats that tell a story of a servers performance. These two will surly be in future greenLight ( http://www.axceler.com/products/greenLight/ ) demos ;)
