1. A system comprising:

  • a processor;

    a bottleneck analyzer that;

    identifies a workload processed by an application, said workload having multiple instances;

    captures timestamps each time a workload instance encounters each of a plurality of checkpoints in said application; and

    for a first checkpoint, curve fits said timestamps across a plurality of workload instances to generate a first historical curve;

    for a second checkpoint, curve fitting said timestamps across said plurality of workload instances to generate a second historical curve; and

    compares said first historical curve to said second historical curve to identify a difference between said first historical curve and said second historical curve; and

    determines that said difference indicates a bottleneck.
