- Kiwi performs much better than Juniper GA, response times for check-ins are <900ms, checkout <1500ms, with not much variation between 1 and 20 users
- Database performance is better and uses much less CPU compared to Juniper GA
- Worst-performing APIs are still POST /checkin-by-barcode and POST /checkout-by-barcode. The response time are still about 500ms. GET /circulation/loans also takes more than 200ms. GET /inventory/item (by barcode) takes less than 100ms now.
- Longevity test shows response times worsen over time, probably due to the growing DB CPU utilization.

In general there is no regression in performance. The response times between Kiwi and Juniper are very close to each other for 1-8 users load unless they were in the 95th percentile group or the 20 users load where Kiwi clearly out-perform Juniper. In the tables below, the Delta columns express the differences between Juniper and Kiwi releases in percentage. Any percentage +/-5% is not statistically is within the margin of error. It is also noteworthy that Kiwi seems to invoke the GET /automated-patron-blocks 3 times instead of once
