throttle removed from FreeBSD ports - alternatives?
Hi all, I am using "throttle" for snapshot backups. It is a small utility reading from stdin and writing to stdout and used to limit the speed (to avoid "hammering" of disks and networks) E.g. "throttle -1M" reads 1 MByte/sec. Unfortunately this utility was removed from the FreeBSD ports. I do not know the background. It is nowhere maintained anymore, it seems (if I get the change log right, it was part of a "bulk retirement commit" in FreeBSD) I am exploring and considering options.. Do you know any alternatives? Regards Peter

pipeviewer (pv) has a rate-limit option as well: http://www.ivarch.com/programs/pv.shtml Though it's primary function is to show how fast the pipe is moving data The page has FreeBSD support listed in FreshPorts hannah

In case you're curious, the reason cited in the 2014-02-10 removal was 'Mark as deprecated unmaintained ports for which no public distfiles are available for part or all the needed distfiles.' http://svnweb.freebsd.org/ports?view=revision&revision=343626 -- Cheers, Cuius testiculos habes, habeas cardia et cerebellum.

If it's at the file layer, rsync has --bwlimit. For block layer, I tend to just ionice -c3 so that other processes get priority over it. I've never had to care about "overloading" the disk itself. For networks, I rely on current generations of OpenSSH setting the TOS of noninteraction connections to "I'm bulk traffic!", and routers' default qdisc (tc-pfifo_fast) to bucket it accordingly. BUT, for the latter two paragraphs, my results are not optimal :-)
