PERF-146 - Getting issue details... STATUS

Overview:

The purpose of these tests is to compare results from two identical test runs on different environment. Find the reason of slownesses if any will be there.

Summary:

Bot system shows stable work, and test passed without errors. Environments has a different logic on modules usage, so there is a difference in response times there.

GCP1 env. shows faster response than BHS1, less than 10 milliseconds difference on 75 percentile and less than 50 milliseconds on 95 percentile.

It's not a big difference, however with such request per second rates it causes a visible difference in total count of calls.

Version:

mod-circulation:19.2.7;
mod-circulation-storage:12.1.4;
okapi:4.3.3;
mod-inventory-storage:19.4.4.
