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

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs

1. Navigate to http://nodejs.org/download/ and on the Linux Binaries (.tar.gz) row click to download the 64-bit version of the current latest release.

2. Say you've downloaded node-v0.10.7-linux-x64.tar.gz into the Downloads directory. Then, open the terminal and type the following:

$ cd ~/Downloads
$ mkdir -p ~/local/node
$ tar xzf node-v0.10.7-linux-x64.tar.gz -C ~/local/node --strip-components=1
$ echo '# Node Enviroment Setup' >> ~/.bashrc
$ echo 'export PATH=$HOME/local/node/bin:$PATH' >> ~/.bashrc
