In ClientConfig Javaoc says that the client will use Runtime.coresAvailable / 2 (let's say N = cores / 2), that means that must be N Volt Network Threads and N Volt Reaper Threads ? Or N/2 "Volt Network Threads and N/2 Volt Reaper Threads ?
I work at VoltDB. There is a discrepancy in the Javadoc, the formula is actually max(1, (cores/4)) for the number of Volt Network threads. The thread names will be "Volt Client Network - 1" and subsequent numbers. Each client will have a single "VoltDB Client Reaper Thread".
