An important missing piece of the RCTL resource limits + framework was the ability to limit file system 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, and + adding a new throttling mechanism, to slow down offending + processes when a limit gets hit.

+ +

The code has been committed and will ship with &os; + 11.0-RELEASE.

+ + + + +

Additional testing

+
+ + +

Simplify locking, getting rid of rctl_lock altogether

+
+ + +

Improve statistics gathering by make it possible for + rctl -u to retrieve usage counters at a fixed point + of time

+
+ + +

Use the new throttling mechanism for %CPU limits
