Googling for contemporary speeds ... HP ... 36 MB/s DLT ... 80 MB/s LTO
... well, i'd need a new computer first.

How come that the time granularity of the backup processing chain
does not get finer as the systems get faster ? Since our fifos 
are mainly having an averaging effect, a finer granularity would
avoid the need to make them larger. But we clearly have to enlarge
them. We still have to prepare for a few realtime seconds of shortage.

There must be something negative growing with our faster systems. 
More processes which impose disturbance ? Larger amounts of disk data
and therefore larger disturbances ?
Compression ratios staid more or less the same. 2:1 as rule of thumb.


For something else:
In

i ask wether the current behavior of cdrecord with padsize= and
multiple tracks will be uphold or wether it will be changed to
comply to the man page.
A short answer would be welcome.


Have a nice day :)
