Adding on to what others have said, indexing speed in general is largely affected by the parallelism and isolation you can give to each node. Is there a reason why you cannot have more than 1 shard? If you have 5 node cluster, why not have 5 shards, maxshardspernode=1 replica=1 is ok. You should see dramatic gains. Solr’s power and speed in doing everything comes from using it as a distributed system. By sharing more you will be using the benefit of that distributed capability,
