Have you enabled compression? could you show us more metric info about data locality?
and maybe there're lots of running compaction activities?
and could you tell us read/write countPerSecond and estimated kv size?
It needs more detail info, i think:)

主题: Save the bandwidth usage
We are tuning a HBase cluster, it seems the current limitation is on
network bandwidth usage during a performance test, the bidirectional
bandwidth usage(sending+receiving) between our nodes is around 1Gb and
almost hit the limitation(we had a pure network test before), so any ideas
on how we can improve this?
