I have noticed that all network connections are slow to start . But have normal responsiveness after the connection has been negotiated . This all network activity . I do have two nics in my system . One eepro100 driven & one ns38320 driven . My MB is a Tyan thunder s2567 . When I was running 2.4.21-rc3 the starting of the connections seemed avaerage but since there has been a Markedly slower response to connection establishment .
