Postgres Sizing

PostgreSQL performance is generally limited by the number of CPU cores and Memory available. It is recommended that the storage backing Postgres be low-latency (SSD) and capable of high throughput.

The following table provides a general guideline for sizing your PostgreSQL instance based on the number of collectors.

Collector Count	CPU Cores	Memory	Disk (GB)
1-60,000	4	16GB	60
60,000-125,000	8	32GB	120
125,000-250,000	16	64GB	180
250,000-500,000	24	48GB	240
500,000-1,000,000	32	64GB	300
