[talk] A cool commit for ZFS

[Isaac (.ike) Levy]

Pretty amazing IMHO, ZFS I/O limits,

https://lists.freebsd.org/pipermail/svn-src-head/2016-April/084288.html

"  Add four new RCTL resources - readbps, readiops, writebps and writeiops,
 for limiting disk (actually filesystem) IO.

 Note that in some cases these limits are not quite precise. It's ok,
 as long as it's within some reasonable bounds.
"

Best,
