Load Testing · Senior · Question 22 of 76
Staging is half the size of production. Can you double staging results to predict prod?
- 1No: scaling isn't linear, and bottlenecks may differ
- 2Yes, as long as the database is the same size
- 3Yes: capacity always scales exactly with servers
Show the answer
Correct answer: No: scaling isn't linear, and bottlenecks may differ
Explanation
Shared resources like DBs, caches and network don't scale with app servers. Use staging for trends and regressions, and validate capacity on prod-like setups.
