Yes, we have one server connected to our network and all the clients connected to the sever via a switch. The server has gigbit but not the switches and maybe not our upstream network switches. I'll have to run this option by our network people and see if it's doable. Thanks for the info. > > Are you sure network bandwidth is the issue though? What makes you think > that?

It happens whenever students are all using the internet. Could be firefox itself. I don't know how to test if we are maxing bandwidth but with one 100MB line coming in it seems likely. I'll check out the munin tool. Thanks, Jim -- Please avoid sending me Word or PowerPoint attachments.
