===== Why is simultaneous burning with multiple drives so slow ? ===== #concurrent_burn
It is a known regression of Linux since about 2010 that operating more than
one drive at the same time via SCSI commands shows severe throughput problems.
See [ConcurrentLinuxSr the wiki page about this problem] which offers a
workaround in userspace (your milage may vary), explanantions of the
reason, and a link to a remedy proposal by courageous kernel modification.
