Answer
Use good shard keys, bulk writes, avoid unnecessary indexes, keep documents small, and tune WiredTiger cache.
Quick Answer
High write throughput optimization: use bulk writes (bulkWrite() - fewer round trips), avoid per-document indexes (indexes slow writes), use unordered bulk inserts (continue on error, parallel), distribute writes across shards with a good shard key, avoid transactions where possible (they add overhead), use write concern w:1 if you can tolerate some risk, and benchmark WiredTiger cache size.
