Postgres Sizing
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 | 48GB | 180 |
| 250,000-500,000 | 24 | 48GB | 240 |
| 500,000-1,000,000 | 32 | 64GB | 300 |
