Hi, First, this performance (48ms) is not necessarily bad at all. Make sure when running tests, to start from the same state, newly started servers, and use the same test suite, running for the same duration, preferably 10+ minutes. Else various caches may play games with you.
There is very little overhead in SolrCloud when it comes to a 1-shard collection, it quickly delegates to the local index on the node receiving the query. Can you share how big the index is on disk and how much physical RAM you have on the server? You do not reveal whether you query one of the replicas or attempt load balancing. You could consider benching a 1-node solrCloud cluster first to simplify it all.
