Set the read timeout to @var{seconds} seconds. Whenever a network read Set the network timeout to @var{seconds} seconds. Whenever Wget
is issued, the file descriptor is checked for a timeout, which could connects to or reads from a remote host, it checks for a timeout and
otherwise leave a pending connection (uninterrupted read). The default aborts the operation if the time expires. This prevents anomalous
occurrences such as hanging reads or infinite connects. The default
timeout is 900 seconds (fifteen minutes). Setting timeout to 0 will timeout is 900 seconds (fifteen minutes). Setting timeout to 0 will

@cindex limit bandwidth
@item --limit-rate=@var{amount}
Limit the download speed to @var{amount} bytes per second. Amount may
be expressed in bytes, kilobytes with the @samp{k} suffix, or megabytes
with the @samp{m} suffix. For example, @samp{--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 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 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.
