Experience with Domino on a AS400

Hallo all,

who has experience with Lotus Domino on a AS/400 with single processor

we have a 720 with one processor and os/400 V5R1

the server has 2500 MB RAM
and 130 GB RAID 5

on this runs lotus Domino R 5.0.8

on our machine there are 250 users - on server are 1600 Server.users

The use of capacity is at our busytime from 7:00 to 17:00 the most time on
++++ over 99,9 percent

It is not a dedicated server, it´s a "normal" iseries.

Have anyone such problems too?

More Informations:

on this AS/400 only runs Domino. Nothing other applications.

Under Domino we only work with mailfiles, calender and database
(selfcreated templates) - it have only more fields, a history and since two
weeks the swing integrator.

No application such like dochouse, intraware etc.

The only one what is running is the TrendMicro ScanMail for AS/400 Release
2.5.


It´s different which tasks have a high CPU.

There are fife tasks: server, router, mtc, update and tmmscan

Server  -  MTC - Router - Update - tmmscan - time

18,1        29,2   2,2   27,3      18,0         10:14:19

The CPU % are between 99,8 and ++++

There are 1.101 Server.User, the Server.AvailabilityIndex is between 96 and
100,

What I have seen in the administration Client is, that ca the half of our
users are under Server - Status - Users have mor than one or two entries.
Any have until over 70 entries - but these are the less. The most of them
have 5 to 12. From thies entries, only one ore two have one database(s)
open entries, all others without entries under Database(s) open and Minutes
Idle

Thanks
