The basic setup
Concurrent threads: 5, 10, 15, 20, 25,
100 concurrent users don't necessarily mean heavily loaded. Try 5000
concurrent users or something even higher. Keep in mind the
bottleneck will be your database, so try to figure what 100 concurrent
users means in terms of peak and average concurrent requests.
