Reading back the thread here and reminding myself of what we discussed I guess the next step is to hash out a proposal for the user list and get some feedback?
{quote}{quote} I'd personally prefer to hash out here for a week or so, to get a good proposal to take to the user list, or a couple of competing proposals. I find public engagements works best when there's a good case to challenge/consider.

> We have a bunch of inconsistent names and config patterns in the codebase, both from the yams and JVM properties.  It would be nice to standardise the naming (such as otc_ vs internode_) as well as the provision of values with units - while maintaining perpetual backwards compatibility with the old parameter names, of course.
> For temporal units, I would propose parsing strings with suffixes of:
> {{code}}
> u|micros(econds?)?
> ms|millis(econds?)?
> s(econds?)?
> m(inutes?)?
> h(ours?)?
> d(ays?)?
> mo(nths?)?
> {{code}}
> For rate units, I would propose parsing any of the standard {{B/s, KiB/s, MiB/s, GiB/s, TiB/s}}.
> Perhaps for avoiding ambiguity we could not accept bauds {{bs, Mbps}} or powers of 1000 such as {{KB/s}}, given these are regularly used for either their old or new definition e.g. {{KiB/s}}, or we could support them and simply log the value in bytes/s.
