In an embodiment, virtual trace records are read and physical trace records are created and displayed. The virtual trace records are associated with virtual processors allocated to logical partitions in a logically-partitioned computer system. Each of the virtual trace records has a wait timestamp, specifying a time at which a virtual processor began waiting to be dispatched and a wait time delta, specifying an amount of time that the virtual processor waited to be dispatched. An execute timestamp is created in each of the virtual trace records, which specifies a time at which the virtual processor was dispatched. The virtual trace records are sorted for each of the virtual processors by the execute timestamp. Physical trace records are created based on the sorted virtual trace records. Each physical trace record describes a dispatch of one of the virtual processors to one of the physical processors.
