In a more perfect world, the dispatcher would get the CPU to programs that do not hog it and that do i/o on an expedited basis. I remember amazing operators who were copying tape with the difference if I made the job APRIOR, which meant real time. The drive went from "bup bup bup" to "ZZZZZZZZ", and nobody suffered, because it was i/o bound. Programs like that need to take their 1% off the top, which is no harm to the 99%, especially when there is still idle time. Writing dispatches is a big deal some places. One sysadmin refused to kill a looping pg for me, because he said their very custom dispatcher ensured that the CPU it took was off the bottom, so they had a policy to just wait for the periodic reboot.

bup-server
bup-server(1) General Commands Manual bup-server(1)
NAME
bup-server - the server side of the bup client-server relationship
SYNOPSIS
bup server
DESCRIPTION
bup server is the server side of a remote bup session. If you use bup-split(1) or bup-save(1) with the -r option, they will ssh to the
remote server and run bup server to receive the transmitted objects.
There is normally no reason to run bup server yourself.
MODES
smart In this mode, the server checks each incoming object against the idx files in its repository. If any object already exists, it
tells the client about the idx file it was found in, allowing the client to download that idx and avoid sending duplicate data.
This is bup-server's default mode.
dumb In this mode, the server will not check its local index before writing an object. To avoid writing duplicate objects, the server
will tell the client to download all of its .idx files at the start of the session. This mode is useful on low powered server hard-
ware (ie router/slow NAS).
FILES
$BUP_DIR/bup-dumb-server
Activate dumb server mode, as discussed above. This file is not created by default in new repositories.
