- 2Every doubling of servers exactly doubles the throughput
- 3The serial part of the work limits the speedup from more resources

Correct answer: The serial part of the work limits the speedup from more resources
Explanation
If 10% of the work can't be parallelized, the speedup can never exceed 10×. Shared locks and single DB writers are typical serial parts.
