Question About COPY command in 3 nodes Cluster vs 1 standalone node

edited July 2017 in General Discussion

I have 3 nodes cluster and a standalone node too and want to test load data with COPY command in each of them ...

I have 10 files with 1 million rows and put them into first node of cluster and also in standalone node .

COPY command in 3 node cluster and standalone for same file, takes 50 second ...
so I don't see any optimization in 3 node Cluster
what is the problem ?
