This page is deprecated, please see the actual report here: [Nolana] Check-IN + title-level requests
Overview
Test goal is to assess performance of circulation check-in functionality for users with 10 TLR (title-level requests) each.
Ticket: PERF-350 - Getting issue details... STATUS
Summary
Load tests showed that there is no significant difference in performance of users with TLRs and without it.

There are several spikes during test with 1 user load. This can be caused by background jobs, as such behaviour wasn't reproduced during other tests.

Methodology/Approach
- Conduct necessary commands to return the database to the initial state. Do this before each test run. Wait several minutes before the test start.
- Conduct check-in load tests with different number of users.
- Repeat tests with the same approach but before each test also generate 10 TLR for each user by running JMeter script (Create_TLR.jmx).
- Compare test results.
