Did it have a positive effect on the Solaris
machine ?

According to Andy's text i assume that the media
was formatted automatically and thus would at
most be written at half its nominal speed.
4.5 MiB/second.

But the reported performance was less than one
third of that half. Still very mysterious.

That's what i read from the text.
(I have my own burn programs to test. Thus i
use them at any occasion i have with BD media.
One year of BD burning strengthened my opinion
that at least my drive and my media work well
with full nominal 2x speed.)

I would omit the -speed option and let growisofs
negotiate that with the drive. Afaik -speed is
rather intended to slow down poor media.


Have a nice day :)
