If an attacker sends a large number of SYN requests with fake source addresses, the server side will consume a lot of resources to handle this semi-connection, and saving traversal will consume a lot of CPU time and memory, not to mention retrying SYN + ACK on IP in this list. TCP is a reliable protocol, and messages will be retransmitted at this time. The default number of retries is 5. The interval time of retries is doubled from 1s to 1s + 2s + 4s + 8s + 16s = 31s respectively. After the fifth time is sent out, it will take 32s to know that the fifth time has timed out, so the total is 31 + 32=63s.
