Unicorn + Runit + RVM
#!/bin/bash -e
#
# Since unicorn creates a new pid on restart/reload, it needs a little extra love to
# manage with runit. Instead of managing unicorn directly, we simply trap signal calls
# to the service and redirect them to unicorn directly.
#
# To make this work properly with RVM, you should create a wrapper for the app's gemset unicorn.

Elasticsearch - Index best practices from Shay Banon
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
