A bounce buffer defeats the entire purpose of using RDMA in these cases.
When using RDMA for very large transfers like this, the goal here is to map
the entire memory region at once and avoid all CPU interactions (except for
message management within libibverbs) so that the NIC is doing all of the
work.
I'm sure rsocket has its place with much smaller transfer sizes, but this is
very different.
To clarify, are you actively using rdma based migration in production? Stepping
up
to help maintain it?
Yes, both Huawei and IONOS have both been contributing here in this
email thread.
They are both using it in production.
