+
+В cURL и Wget имеется параметр `limit-rate`
+для установки максимальной скорости загрузки.
+
+Информация с [man.freebsd.org](https://man.freebsd.org/cgi/man.cgi?wget).
+
+```text
+--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  is  useful  when,  for  whatever
+       reason,  you  don't  want  Wget  to  consume  the  entire available
+       bandwidth.
+
+       This  option  allows  the  use  of  decimal  numbers,  usually   in
+       conjunction  with power suffixes; for example, --limit-rate=2.5k is
+       a legal value.
+
+       Note that Wget implements the limiting by sleeping the  appropriate
+       amount  of  time  after  a  network  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 may take some time for this balance to be achieved,  so
+       don't be surprised if limiting the rate doesn't work well with very
+       small files.
+```

+Пример команды:
+
+```sh
+wget -c --limit-rate=500K https://iiiypuk.me/Koe_no_Katachi.mkv
