Load Testing · Senior · Question 25 of 76
Client-side p95 is 900 ms, but app server metrics say 200 ms. Where may the time go?
- 1Before the app: LB queues, connection setup, TLS or the network
- 2Nowhere: the client tool always adds exactly 700 ms
- 3Into the database, because app metrics exclude DB time
Show the answer
Correct answer: Before the app: LB queues, connection setup, TLS or the network
Explanation
Server metrics start when the app gets the request. Waiting in a proxy queue or accept backlog is invisible to it. Compare timings at each hop.
