Date: Thu, 10 Oct 2013 10:23:33 -0400 From: William Thompson <wt@...ctro-mechanical.com> To: linux-kernel@...r.kernel.org Subject: Burning multiple CD/DVDs at one time is slow (3.4.55 x86_64) Please keep me in the CC. I tried burning 2 DVDs at the same time. Both processes completed however there were buffer underruns and the speed was no more than 4x. Each burner individually can do upto 16x and I have seen the burn end at 16-17x. The parallel burns ended no higher than 6x. Why is this so slow? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
