Description

Stream sessions with a remote are bound to a single thread, and when compression is in use this thread can be CPU bound, limiting throughput considerably. When the number of nodes is small (i.e. when the number of concurrent sessions is also low), rebuilds or bootstrap operations can take a very long time.

Ideally, data could be streamed from any given remote concurrently.
