I am writing a client-side application which
connect() to a server and close it in a for loop.
connect() is done in blocking-mode, and I found that some
connect() call will block for about 3 seconds after thousands of successful
I used tcpdump and found some strange result: after I called the
connect(), SYN was not sent for about 3 seconds.
PS. I am on 64-bit Ubuntu, kernel 3.0.0-13.
