My context is this: one vserver runs a popular web site, and on another
one, occasionally I shift multi-gig files around, with cp. When I'm doing
that, the website vserver grinds to a halt - well, responds to requests
quite slowly anyway.
Instead of cp I use rsync --bwlimit=7000, which throttles I/O to a bit less
than 7MB/s. Works for local disk-to-disk copying, and works quite well.
There's always a workaround, but that's the same as renice'ing processes
on one vserver to be cognisant of the needs of another vserver. It's
what the CPU limiting handles, so vservers can be more autonomous.
