This is because the server needs to retransmit the syn + ack message and wait for the client's confirmation message until the tcp connection timeout. This state of waiting for the client to confirm the connection is usually called a half-open connection. The half-open connection will be kept in the connection table of the server until the connection is disconnected.

As mentioned above, SYN attacks can be prevented by increasing the backlog queue. In addition, reducing timeout time also enables the system to process more SYN requests. We know that the timeout timeout, that is, the half-connection lifetime, is the sum of the timeout times that the system waits for all retransmissions. The larger this value, the longer the half-connection takes up the backlog queue and the fewer SYN requests the system can handle. In order to shorten the timeout time, it can be realized by shortening the retransmission timeout time (usually the first retransmission timeout time) and reducing the number of retransmissions.
