Hi,  
I have data nodes across 2 VLANs. Is my indexing performance will be affected ? I am indexing nearly 4.5 TB (primary+replica) ~5 billion messages per day. 44 data node instances (22 machines each with 128GB RAM - running 2 instances per machine). I am seeing indexing performance are affected. I have seen little improvement after setting

1. index.store.throttle.type=none
2. index.merge.scheduler.max\_thread\_count=1

But still indexing was not getting catch up .

Are the VLANs in the same datacentre?
