Don’t forget about the physical nature of a distributed call. The local client get doesn’t go through the switch and the remote client goes through the switch.
As a quick check try a simple ping from one machine to the other and ping local host. Notice how much quicker the local ping to the remote host is. Then check how those numbers correlate to the performance you are getting out of geode. If you would like to aggregate the cost of the network operations - geode has a putAll / getAll / removeAll.
