Wrong units on replication bandwidth limit?

I'm setting up offsite replication on FreeNAS 11.1 and performing initial testing on the same site with a gigabit connection between source & target.

I configured a replication bandwidth limit with a setting of 300 (in theory this is kB/s, which by calculation should equate to 2.4 Mbps, a reasonable use of my DSL link) only to find that even small incremental snapshots were not completing replication in my 6 hour overnight window.

I increased the limit to 300,000 and the replications finished in a reasonable timeframe. This leads me to believe the units in the documentation and the GUI, both on the field label (kB/s) and in the hover help text (kilobytes/second) are incorrect, and they probably should be B/s and bytes/second, respectively. This seems to be backed up by the figures I see in pfsense (Status > Traffic Graph > LAN).

Being new to the community, I thought I'd probe for comments here prior to submitting a bug.

On further testing, it appears the unit should be kbps, rather than kB/s or my earlier guess of B/s. The basis for this:

Replication of a new dataset with 3.1 Gb with a limit setting of 300,000 over gigabit ethernet lasted approx. 90s (yes I used a trusty stopwatch, how quaint). So 300,000 kilobits / s * 90 s = 27,000,000 kilobits = 3375000 kB = 3.2 Gb - close enough for me.

Will post a bug shortly.
