In this workflow, we are checking the performance of the renewal of loan items for the Goldenrod release.

We tested it with 1, 2 virtual users for 30 minutes.  

Backend:

  • mod-users-17.1.0
  • mod-users-bl-6.0.0
  • mod-authtoken-2.5.1
  • mod-permissions-5.11.2
  • mod-circulation-19.0.9
  • mod-circulation-storage-12.0.1
  • okapi-3.1.1

Environment:

  • 55 back-end modules deployed in 110 ECS services
  • 3 okapi ECS services
  • 8 m5.large  EC2 instances
  • 2 (1 reader, 1 writer) db.r5.xlarge AWS RDS instance
  • INFO logging level

  2. Below is the dependency graph generated from Giraffe for single POST_/circulation/renew-by-barcode API. It shows individual calls made by renew-by-barcode to gather prerequisite data from different APIs such as item-storage, location-units, loan-types, request-storage, notice-policy, locations, and mod-authtoken. In all, this call took 990 ms, and 6% of that is consumed by mod-authtoken and the remaining 94% of the time is taken by other APIs to gather prerequisite data.



Database CPU Utilization

The database CPU usage increases gradually for 1, 2  users run. At maximum 9% CPU usage for 1 user.

Image Added


For 2 users, max CPU utilization increases and then stabilizes as the number of loans increases, mostly because RDS Postgresql is caching the most frequent query results. Therefore, CPU utilization is relatively on the lower side.
