Your question boils down to "if there is more than one shard per node, does it harm search or index speed"?
The answer is, it depends. If you have powerful nodes regarding CPU and RAM and your shards are not too big, you can use more than one shard happily. If you use too many shards per node, you will notice it when you run out of resources. If you plan to use more than two nodes, creating more than 1 shard per index is very welcome so the index can keep up with the node count.
