We setup a cluster with 2 data nodes on Hyper-V VMs.
Daily index size is around 200 GB.
Performance is very poor, elasticsearch does not respond at all.
2 data nodes use 100% CPU and 32 GB of memory (each node).
We use the latest version, 5.3.0 with the latest Java version.
I also observed 400 Mbit/s network traffic between nodes.
We need some guidance on sizing.
Or should we setup Linux nodes instead of Windows?
