Systems

The following systems were used for performance evaluation:

System	Provider	CPU	Cores	RAM	SSD	Heap Mem	Block Cache	Resource Cache ¹	Background Jobs ²	Indexer Threads ³
LEA47	on-prem	EPYC 7543P	16	128 GiB	2 TB	32 GiB	32 GiB	10 M	8	16
LEA58	on-prem	EPYC 7543P	32	256 GiB	2 TB	64 GiB	64 GiB	20 M	16	32

¹ Size of the resource cache (DB_RESOURCE_CACHE_SIZE) ² The maximum number of the [background jobs][3] used for DB compactions (DB_MAX_BACKGROUND_JOBS) ³ The number threads used for indexing resources (DB_RESOURCE_INDEXER_THREADS)

Datasets

The following datasets were used:

Dataset	History	# Pat. ¹	# Res. ²	# Obs. ³	Disc Size
100k	10 years	100 k	104 M	59 M	202 GiB
100k-fh	full	100 k	317 M	191 M	323 GiB
1M	10 years	1 M	1044 M	593 M	1045 GiB

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

The creation of the datasets is described in the Synthea section. The disc size is measured after full manual compaction of the database and can be higher during the import.
