Hi,
I am using ES 1.3.2 and setup a cluster with 3 nodes, having about 350,000
docs right now. (1 shard, 2 replicas)
In my service I create a transport node connecting to the cluster, and use
Java API to search.
Then I benchmarked my service - each HTTP request to my service will
trigger about 12 to 15 queries (sent with multi-search api).
- Without preference set to local, all requests get slow when
concurrency goes high. - With preference set to local, some of the requests are as fast as low
concurrency under high concurrency, but some of them are super slow
So I want to know how does this config affect the performance in my setup
(1 transport --> 3 data nodes).
Also I don't understand why some node can handle the queries very fast
while the others are super slow... I thought in my setup every node should
have complete data stored.
Thanks
