Load Testing

Systems

The following systems were used for performance evaluation:

System	Provider	CPU	Cores	RAM	SSD
A5N46	on-prem	Ryzen 9900X	24	96 GiB	4 TB

All systems were configured according the Tuning Guide.

Datasets

The following datasets were used:

Dataset	History	# Pat. ¹	# Res. ²	# Obs. ³	Size on SSD
1M	10 years	1 M	1044 M	593 M	1045 GiB

¹ Number of Patients, ² Total Number of Resources, ³ Number of Observations

Methods

The load testing tool k6 is used to create load from another host in the same network as the test system.
