A TCP sender can interpret an out-of-order segment delivery as a lost segment. If it does so, the TCP sender will retransmit the segment previous to the out-of-order packet and slow its data delivery rate for that connection. The duplicate-SACK option, an extension to the SACK option that was defined in May 2000 in RFC 2883, solves this problem

Here's a screenshot of Wireshark's TCP window scaling analysis when sending a 25 MB file with random bytes - the window never gets big enough to keep up throughput due to frequent (every 10-20 packets or so) duplicate ACKs or out-of-order ACKs and corresponding retransmissions. It takes around 55 seconds to transfer the file because of this.
