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%
