Description

Currently the rbd import appears to be single threaded which means the import process is being written to a single disk at a time, which limits the import to the throughout of a single disk.

Multithreading the import process could greatly increase the performance of the rbd import.

Reads are single-threaded, but writes are asynchronous, so multiple could be in flight at once. (In rbd.cc, do_import calls AioImportContext::AioImportContext(), which calls librbd::Image::aio_write.)
