gprof will show where CPU time is being spent, but not how much of a framerate increase you can expect. Even for CPU time, it's iffy -- for example, SGPropertyNode::getDoubleValue was showing up high in the profiling stats for JSBSim, but that's because it was invoking a lot of inline accessor methods that weren't profiled (because they were inlined).
