An important missing piece of the RCTL resource limits + mechanism was the ability to limit disk throughput. This project + aims to fill that hole by making it possible to add RCTL rules for + read bytes per second (BPS), write BPS, read I/O operations per + second (IOPS), and write IOPS. It also adds a new throttling + mechanism, to delay process execution when a limit gets hit.

The project is at the late implementation stage. The major + piece of work left, apart from testing, is to integrate it with + ZFS. The project is expected to ship with &os; 11.0.
