I have an app that make connections to an as400 database. It seems that when approx 19 - 20 users are logged on at the same time my app gets real sluggish. It seems to happen when only one user updates the as400 and at that time I do a USE then closeTables then openTables to refresh the dataenvironment. It's when this happens that it's real slow to respond or it takes a press of the escape key or sometimes end with task manager. Any help?
