-dit(bf(--bwlimit=KBPS)) This option allows you to specify a maximum
-transfer rate in kilobytes per second. This option is most effective when
-using rsync with large files (several megabytes and up). Due to the nature
-of rsync transfers, blocks of data are sent, then if rsync determines the
-transfer was too fast, it will wait before sending the next data block. The
-result is an average transfer rate equaling the specified limit. A value
-of zero specifies no limit.
+dit(bf(--bwlimit=RATE)) This option allows you to specify the maximum transfer
+rate for the data sent over the socket, specified in units per second. The
+RATE value can be suffixed with a string to indicate a size multiplier, and may
+be a fractional value (e.g. "bf(--bwlimit=1.5m)"). If no suffix is specified,
+the value will be assumed to be in units of 1024 bytes (as if "K" or "KiB" had
+been appended). See the bf(--max-size) option for a description of all the
+available suffixes. A value of zero specifies no limit.
+
+For backward-compatibility reasons, the rate limit will be rounded to the
+nearest KiB unit, so no rate smaller than 1024 bytes per second is possible.
+
+Rsync writes data over the socket in blocks, and this option both limits the
+size of the blocks that rsync writes, and tries to keep the average transfer
+rate at the requested limit. Some "burstiness" may be seen where rsync writes
+out a block of data and then sleeps to bring the average rate into compliance.
+
+Due to the internal buffering of data, the bf(--progress) option may not be an
+accurate reflection on how fast the data is being sent. This is because some
+files can show up as being rapidly sent when the data is quickly buffered,
+while other can show up as very slow when the flushing of the output buffer
+occurs. This may be fixed in a future version.
