<p>In the era of 300&nbsp;bit/s modems, a packet took about four seconds to send, and typical latencies were on the order of  of a second, so the performance overhead was not significant. As speeds increase the problem becomes more problematic; at 2400&nbsp;bit/s a packet takes about 0.55&nbsp;seconds to send, so about  of the available bandwidth is wasted waiting for s. At 9600&nbsp;bit/s a packet requires only 0.13&nbsp;seconds to send, so about  of the bandwidth is wasted.</p>
