windows 2019 storage replica, low replication speed 1Gb/s

Question

Hi,

I have a question about storage replica for windows 2019. Namely, I have a cluster cluster replication connected by several 10Gb networks and I have allocated one of these networks for replication. Initialization replica works at full 10G speed, while during operation I noticed that it works much slower and uses a maximum of 1Gb in every situation, which strongly limits the possibilities of the entire cluster. After switching replication to another network, it's just 1Gb that's all. Regardless of the type of replication, whether synchronous or asynchronous is the same. On SMB I don't have any speed limits, qos are disabled etc. What could be the reason?

Answer 1

Hi,
I did some research but I didn’t find much about storage replica limitations.
However, I did find an article about improving replication performance.
