8 nodes Cluster with Aerospike 3.3.17 In-Memory, Replica = 2. Single C Client with multiple threads on a separate node to send Write traffic (in the same internal Switch).
The network latency by PING has stable 0.15ms.
#Threads TPS Average Latency 1 1.7K 0.57ms 2 3.6K 0.55ms 10 37K 0.27ms 120 307K 0.39ms
Why the latency with #Threads = 1 is so large? (0.57ms) As comparison, the local Write on a single node has average latency 0.07ms.
I noticed the number of sockets on client side to remote port 3000 was dynamically changed (up to hundreds).
