A few things to note:
- GET_/inventory/instances and GET_/instance-bulk/ids have the slowest response time. Have failed responses even for 1 user
The workflow with more than 100K records become unresponsive became non-responsive even with 1 user
- The workflow with more than 5 users become unresponsive
...
- became unresponsive at times during the test runs, more on that below.

These services for the selected modules were chosen for their activity in the workflow and prominent values compared to other modules.
Data were obtained from the 30-min test runs

3. Memory trends
Folio build was deployed with 50+ ECS services installed randomly across 4 m5.large instances in the fcp1-pvt cluster and the database was created on the db.r5.xlarge AWS RDS instance. Logging level was set to default INFO.
According to the capacity performance test results, we can say that the saturation point was caused by high CPU utilization on one of four nodes in the fcp1-pvt cluster.
Based on the CPU usage per service we can make a conclusion that the most consuming service was mod-inventory-storage.
The test run with 5 users and 10K~50K instances
The service is 99% of allocated RAM memory.

The test run with 5 users and 10K~50K instances
Fig 2.2: CPU utilization of various modules running on an EC2 instance, including mod-inventory-storage
Based on this CPU usage chart (Fig 2.2) we can make see that the service consumed the most CPU resources was mod-inventory-storage.
3. Memory Usage
The following data shows memory consumption of ECS services, most notably of mod-inventory-storage during the 5 users and 10K-50K instances retrieved test run.
Fig 3.1: mod-inventory-storage service consumed 99% of allocated RAM memory in the 5 users and 10K-50K instances retrieved test run.
The diagram below shows mod-inventory-storage crashed a few times due to OOM. There are were 4 instances of mod-inventory-storage active in this test run. This means that it crashed 3 times and spun up new mod-inventory-storage instances

JVM Profiling result
CPU JVM profiling of the most resources consuming mod-inventory-storage service showed 6 methods which had a high CPU usage and impact on the overall service performance.
...
fasterxml.jackson.databind.ObjectMapper.readValue method uses most of CPU capacity which leads to performance degradation
Summary

Summary
...
- FOLIO performs better without being profiled when the tests are running
Issues
- Most of failed requests were related to GET_/inventory/instances and GET_/instance-bulk/ids that use mod-inventory-storage serviceGET_/inventory/instances and GET_/instance-bulk/ids have failed responses even for 1 user (30 min test run), even in a 1-user 30-min test run.
- mod-inventory-storage used significant memory on a machine with 8GB RAM to return 50K to 100K records.
- mod-inventory-storage was crashing a few times due to OutOfMemoryError to OutOfMemory exception during the test runs
The workflow with that retrieves more than 100K records become became unresponsive even with 1 user
- The workflow with more than 5 users become unresponsiveMemory Issues: mod-inventory-storage has noticeable to significant gains in memory used. more than 5 users became unresponsive
- fasterxml.jackson.databind.ObjectMapper.readValue method of mod-inventory-storage storage service overuses consumed high CPU resources as there are were a lot of JSON decoding, this implementation could be reviewed and improved to reduce operations with JSONfor optimization possibilities.
- FOLIO performs better without being profiled when the tests are running
