Network Speed between ES nodes

Elastic Stack Elasticsearch
1

Hi,
I have setup a five node cluster (5 shards 1 replica) for evaluation. I
have notice that during a shard relocation or during a cluster rebalance a
node can achieve a maximum speed of 160 Mbp/s.
The issue is that the nodes are communicate through Gigabit Ethernet and
for scp operations i can achieve 560 Mbp/s which is the expected. I haven't
limit the bandwidth from the configuration.
Does anyone has any idea why this might happen?

Thank you,
Antonis

Hey,

judging from a quick peek in the source, I think you have to
set indices.recovery.max_bytes_per_sec settings to something more than the
default, which is 20 MB/s (perfectly matching your 160 MBit/s).
