Re: Why actual speed is slower than nominal? (2.6x vs 4x)
Very useful! Thanks a lot!
It actually seems like even with large files (100s of mb's) the speed
is far from nominal at least on my system.
Would it be possible to somehow mention this little buffering program
on the official growisofs page? I have read that manual quite
carefully, and this was one of the unfortunate cases where RTFM did not
help too much. On the other hand, mastering images to harddrive before
writing them to a DVD is so yesterday ...
