buffer sporadic binary I/O for faster tape use

|

This is a program designed to speed up writing tapes on remote tape
|
||||
drives. Requirements are shared memory and locks which normally
|
||||
means that these are supported in your kernel.
|
||||
|
||||
[for FreeBSD, this means you MUST have a kernel with
|
||||
options SYSVSHM
|
||||
compiled in - markm]
|
||||
|
||||
Buffer has been tested under SunOS 4.0.*, SunOS 4.1.*, Solarix, HP-UX 7.0,
|
||||
and Gould UTX 2.1A (sv universe).
|
||||
|
||||
The program splits itself into two processes. The first process reads
|
||||
(and reblocks) from stdin into a shared memory buffer. The second
|
||||
writes from the shared memory buffer to stdout. Doing it this way
|
||||
means that the writing side effectly sits in a tight write loop and
|
||||
doesn't have to wait for input. Similarly for the input side. It is
|
||||
this waiting that slows down other reblocking processes, like dd.
|
||||
|
||||
I run an archive and need to write large chunks out to tape regularly
|
||||
with an ethernet in the way. Using 'buffer' in a command like:
|
||||
|
||||
tar cvf - stuff | rsh somebox "buffer > /dev/rst8"
|
||||
|
||||
is a factor of 5 faster than the best alternative, gnu tar with its
|
||||
remote tape option:
|
||||
|
||||
tar cvf somebox:/dev/rst8 stuff
