The parent is asking how comes async I/O can handle higher volumes of requests given it's single threaded and even if it does how comes the database is still not the bottleneck. I answered both of these questions.
- coldtea 9y agoYes, and I had an objection with the answer to the second question, that it might leave the impression to the parent that sharding or replication and pooling is required to have good DB IO performance with multiple Node processes -- when in practice it might or might not be an issue. You can have a 12-processes node cluster and still not need a second db.
