主题: [sheepdog-users] sheepdog data write performance with 5 node

 

I have 5 sheepdog nodes with 2Gbps NIC(bonded with 802.3ad mode)

 

I use iftop to monitor the network bandwidth

 

When I write data to sheepdog disk, there are 3 nodes receive data at the
same.

 

Why the sheepdog gateway don’t send to the other 2 node to improve the
performance?
