When I run a load test against ESRestClient with 15 threads running in burst mode using soap UI I keeping getting a lot of these exceptions
java.util.concurrent.TimeoutException
at org.apache.http.nio.pool.AbstractNIOConnPool.processPendingRequest(AbstractNIOConnPool.java:364)

I have a 8 core processor and 32 GB ram. I have allocated 4G of ram to this application.
I have increased the timeout also increased the number of threads but makes no difference.
I have run the same load directly against ES 5.1.2 it seems to be doing well.
So what are the workarounds if there are any? Is there a recommended configuration ?
