Yes. Emulate traffic latency using IPFW and dummynet[^1]. There is no Linux (or OpenBSD, NetBSD) counterpart.

The ZFS implementation is less buggy.

That is not really accurate? Linux traffic control (tc, [0]) exists since Kernel 2.2. It can introduce traffic latency and a few other network conditions, like packet loss.

You can emulate latency, packet errors, etc using netem tc [0] on Linux.

FreeBSD and Linux have been using the same implementation of ZFS for years.

What I really want is the Windows tool for that. Can't call it equivalent, because clunsy is way superior.
