Missed that one.  Thanks!

man wget:

       --limit-rate=amount
           Limit the download speed to amount bytes per second.  Amount may be expressed in bytes, kilobytes
           with the k suffix, or megabytes with the m suffix.  For example, --limit-rate=20k will limit the
           retrieval rate to 20KB/s.  This kind of thing is useful when, for whatever reason, you don't want
           Wget to consume the entire evailable bandwidth.

           Note that Wget implementeds the limiting by sleeping the appropriate amount of time after a net­
           work read that took less time than specified by the rate.  Eventually this strategy causes the
           TCP transfer to slow down to approximately the specified rate.  However, it takes some time for
           this balance to be achieved, so don't be surprised if limiting the rate doesn't work with very
           small files.  Also, the "sleeping" strategy will misfire when an extremely small bandwidth, say
           less than 1.5KB/s, is specified.
