Overview

The following document contains information about FHIR servers performance: Hearth and HAPI FHIR. Tests contain create, update and read actions on a location resource. Each section presents the request structure and response times. To execute tests, the Taurus tool has been used. The following machine has been used for tests:

Memory: 7.7 GiB
Processor: Intel Core i7-6700HQ 2.60GHz x 8
Graphics: GeForce GTX 960M/Pcie/SSE2
OS: Ubuntu 18.04.1 LTS (64-bit)

The following variables have been set and used to avoid duplication in tests. Some of them are used in request bodies.

fhir-server-url: http://192.168.88.183/fhir/Location (Hearth)  |  http://192.168.88.183/hapifhir/baseDstu3/Location (HAPI FHIR)
scenario-iterations: 1000 # how many times a scenario/test will be executed
scenario-concurrency: 1 # how many users will execute the given scenario/test
identifier_value: # this value is generated for each location resource so searching by identifier always returns a single resource
location_id: # set by a FHIR server when a resource is created

Create a new location

Note: When an X test is being executed, there are X - 1 resources in the FHIR server. For the first resource creation, the FHIR server will not contain any resources.
