NAME
writebuffer - write output to devices which don’t like constant
stopping and starting
SYNOPSIS
writebuffer [--mlock] [size]
DESCRIPTION
writebuffer reads data on standard input and writes it to standard
output. It will buffer internally up to size megabytes and will only
write data when the buffer is at least 75% full or when there is no
more input to fill the buffer.
size may also be suffixed with m, k, or b to indicate that it is in
megabytes (2^20), kilobytes (2^10) or bytes.
It is intended for use in situations where many small writes are
undesirable for performance reasons, e.g. tape drives.
OPTIONS
--mlock
Calls mlock(2) to lock the buffer into memory.
