/** Class: Strophe.WebSocket
 *  XMPP Connection manager.
 *
 *  Thie class is the main part of Strophe.  It manages a BOSH connection
 *  to an XMPP server and dispatches events to the user callbacks as
 *  data arrives.  It supports SASL PLAIN, SASL DIGEST-MD5, and legacy
 *  authentication.
 *
 *  After creating a Strophe.Connection object, the user will typically
 *  call connect() with a user supplied callback to handle connection level

If you want, I can try and help with pointers as to how to improve the indexing speed you get. Its quite easy to really increase it by using some simple guidelines, for example:

- Use create in the index API (assuming you can).
- Relax the real time aspect from 1 second to something a bit higher (index.engine.robin.refresh_interval).
- Increase the indexing buffer size (indices.memory.index_buffer_size), it defaults to the value 10% which is 10% of the heap.
- Increase the number of dirty operations that trigger automatic flush (so the translog won't get really big, even though its FS based) by setting index.translog.flush_threshold (defaults to 5000).
- Increase the memory allocated to elasticsearch node. By default its 1g.
- Start with a lower replica count (even 0), and then once the bulk loading is done, increate it to the value you want it to be using the update_settings API. This will improve things as possibly less shards will be allocated to each machine.
- Increase the number of machines you have so
