hi guys,

## i'm doing a test on bulk-index.

first, i indexed 1million docs into a single machine, with the bulk  
size equals to 5000. the process finished in less than 6min, which is  
quite good!

second, i moved to a cluster environment (5 machines, including the  
machine in the first test), and the same bulk size, but the speed is  
much slower, which runs 12.5min.

is there a way to make the index any faster? (at least the same as the  
single machine test). as i plan to load 200million docs into a 10  
machine cluster. the speed would become unacceptable if the index  
takes to long.

ps, i have routing set in every single request.

--  
any suggestions and advice would be appreciated, thanks!
