I've been using multichain with only one node. Lately my rpc requests are getting slow, especially getaddressbalances and for the transactions using sendassetfrom. After reading Clustering nodes for high availability session, it says we can add Load balancing for reading node for the call like getaddressbalances ( actually I want to improve multicahin performance ). However, I don't know how can I add Load Balancing For reading node into my chain which have been running for a long time.
Please explain how can I do?
