Hi,Wondering how you can use LoadGen to simulate multiple user types? I have 30,000 users about 3,000 of them are Heavy users and the rest are light. I thought you could run multiple Master LoadGen clients one with 3000 heavy users and one with 27000 light users, but this doesnt seem to work (i.e when i get to set up the 27,000 users it already picks up that there are 3,000 users already created and includes these in the test making the total up to 30,000)So i'm guessing i need to configure this all on one LoadGen Client? Is there a way to configure LoadGen so that it sets the correct number of users - should i be doing this with the concurrency setting??? I'm also guessing there is not an easy way to tie the users types to certain DBs?Any ideas greatly received!ThanksEmma

I hope you might have gone through http://www.msexchange.org/articles/Microsoft-Exchange-Load-Generator.html article Vinod |CCNA|MCSE 2003 +Messaging|MCTS|ITIL V3|

Yes i have thanks. But that is a very basic configuration and does nto go into detail about how to run with multiple user types at the same time.I'm wondering if i need to not use the default OUs and instead create all the users in OUs called "light" and "Heavy" and then point the user types to these relevant OUs.
