+   Recommended on Garbage Collection for Pruning Nodes: To maximize sync speed for validators and other network providers that are running pruning nodes, the above settings are recommended. GOGC=900 instructs golang to start garbage collection when heap has grown to 9x, and GOMELIMIT=40GB ensures garbage collection runs whenever memory usage reaches 40GB.
