System requirements for public networks
CPU requirements are highest when syncing to the network and typically reduce after the node is synchronized to the chain head.
Java Virtual Machine size
For Mainnet and testnets, the minimum Java Virtual Machine (JVM) memory requirement is 8GB.
JVM memory requirements are highest when syncing, but will reduce after the node is synchronized to the chain head. Monitor your system to determine your actual JVM memory needs.
We are running 1.4.5 mainnet nodes using t3.large boxes.
We synchronized the 1.4.5 mainnet nodes using t3.xlarge boxes.
Using a larger box while synchronizing speeds up the sync process by giving it more resources. When the sync is completed, the box size can be reduced.
If you are using a more recent release that 1.4.5, resource requirements may have increased.
