Theoretical optimal thread count: 3(where marginal speedup gain drops below 5%)
The graph shows how adding more threads affects performance:
- Blue line shows the theoretical speedup for each thread count
- Green line shows the marginal improvement percentage when adding each thread
- The optimal thread count is where marginal improvements drop below 5%
