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.她看得太专注了，没发现前面香荽已经停了下来，一头撞到她肩膀上，嗳哟一声，摸着鼻子使劲吸气。Weightlifting shoes are not all high heels, but also relatively low, similar to the height of ordinary business leather shoes, with outsole height difference of about 1-2cm.天黑的时候，大苞谷和小灰终于在河边找到高凡进山洞的入口。
