Buffer sporadic I/O for faster tape and pipe throughput
This is a program designed initially to speed up writing tapes on remote tape drives, but may be used as a general pipe buffering utility. Note: You must have SYSVSHM support in FreeBSD kernel. 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.
