For sizing guidance, increasing the number of CPU cores on a VA will improve its performance, but the amount of RAM allocated to the machine must scale along with the number of CPU cores present.
Secure Access requires that you allocate at least 1 GB of RAM for each CPU core on the VA. For example, a VA deployed with two CPU cores should have a minimum of 2GB of RAM allocated to it.
VA Specifications | Maximum Queries per Second at Maximum 80% CPU Utilization |
---|---|
1 CPU, 1GB RAM | 1300 |
2 CPU, 2 GB RAM | 3500 |
4 CPU, 4 GB RAM | 8000 |
8 CPU, 8 GB RAM | 16000 |
16 CPU, 16 GB RAM | 28000 |
