Hi,

We're now in performance test and seeing some unexpected result.

We use Java percolate API

client.preparePercolate().setIndices(index).setDocumentType(projectName).setSource(log).execute().actionGet();

LOGGER.info(duration+"ms for percolation, es time  
"+response.getTookInMillis()+" ms for log "+ log);

and registered one simple rule, input log varies.

sometimes response.getTookInMillis() is more than 2000ms meaning it took  
more than 2 seconds to percolate single log.  
sometimes response.getTookInMillis() is less than 10ms which we expect it  
to be.

Ping responses within 1 ms, network has nothing to do with that  
fluctuation, and we want percolation response time to be stable and fast.

Is there any possible reason?
