We have "hard working" Work Flow server (30 000 processes per day, 200 000 processes alive at same time, hundreds manual work items).
Our WEB Client is very slow.
I started on filtering side : topic http://www.mqseries.net/phpBB2/viewtopic.php?t=3422.
And now I want to ask your opinions about creation additional System dedicated for WEB client. Which impact on automatic processing it will have? Which benefits I will rich for WEB Client?

Yaakov:
How many workitems are you creating for each manual activity? With the kind of load you are processing you would probably see some benefit from a 1 to 1 ratio between activityInstance and wokitem for your manual activities. This could lead to smaller worklists which would be a help.

I have 25-30 users authorized for each WorkItem,
But in WorkList I am always use CURRENT_USER filter for administrators.
When I change Threshold to small (like 100 instead of 1000), I still see the same number of reads in DB. Looks like WF reads all from DB and after cuts by Threshold.
I need to be able to show oldest and newest WorkItems as well. This is a reason for big Threshold. May be I need use dynamic change of filter by date?

I would seriously consider using a virtual user if you can. Generating a workitem takes .02 BWU so generating 30 workitems is costing you some.

This is exactly documented behaviour, Threshold limits network traffic.

Virtual user is a good point, jmac!
I understood that I need limit work list using filtering and not Threshold only as possible. Is it correct?
And what about general point - client dedicated system? Thanks

Yaakov:
If I understand correctly, you currently have a configuration with the WebClient accessing the Workflow Server via a client concentrator. What you are now suggesting is that you want to add a second system to the system group that resides on your webserver.
I really am unsure as to whether or not this will help.
What exactly is the problem, if you have extremely long worklists it would be best that they not be queried often.
Perhaps with a little more information, we will be able to give you some ideas.
