Probably your packet size is too big for the Solr<->Solr default settings. Quick test would be to try sending 10 docs per packet, then 100, then 1,000 etc.
There’s not much to be gained efficiency-wise once you get past 100 docs/shard, see: https://lucidworks.com/2015/10/05/really-batch-updates-solr-2/ Second, you’ll get improved throughput if you use SolrJ rather than a straight HTTP connection, but your setup may not be amenable to that alternative.
