pst 96/09/20 14:25:23 Modified: sys/netinet tcp_input.c Log: If the incomplete listen queue for a given socket is full, drop the oldest entry in the queue. There was a fair bit of discussion as to whether or not the proper action is to drop a random entry in the queue. It's my conclusion that a random drop is better than a head drop, however profiling this section of code (done by John Capo) shows that a head-drop results in a significant performance increase. There are scenarios where a random drop is more appropriate. If I find one in reality, I'll add the random drop code under a conditional. Obtained from: discussions and code done by Vernon Schryver (vjs@sgi.com). Revision Changes Path 1.49 +18 -5 src/sys/netinet/tcp_input.c
