You need a performance monitor to collect the data and understand what is preventing them to run. Without that data, I can only guess. It sounds like one or both have landed in the eligable list and don't get dispatched anymore. If you reduce the size of the virtual machines, things will run better. If you have not tuned your VM system, MDC may need to be limited to avoid taking too much storage (with SET MDC STOR 0M 256M for example). If you have sufficient paging space defined you can overcommit memory by SET SRM STORBUF Rob -- Rob van der Heij Velocity Software http://www.velocitysoftware.com/
