What to test?
1. Regressions in code
Ramp THREADS from 1 to 20 – does response time change exponentially? It should be line or linear.
2. Page-views per day/hour/second (Business requirements)
Ramp THREADS from 1 to n (e.g. 200-1000 or more) and monitor the response time graph when it starts to go up (get your max thread count there). Then for required period of time execute a test with max THREADS to get most page-views count. You can compare this amount with Google analytics real data.

Response time
Response time is the total amount of time it takes to respond to a request for service.
Observers can recall one specific image in an unbroken series of different images, each of which lasts as little as 13 milliseconds

Load
An idle computer has a load number of 0.
Each process using or waiting for CPU (the ready queue or run queue) increments the load number by 1.
Load < 10 = OK
