Thanks Steve..
I'm not measuring performace at all, but I'm loosing connections
sometimes.. occurs with some WAN clients running 64kbps links and even
at LAN. My clients must connect to a partner mainframe via tn3270 (just
telnet, 23, no trouble), but sometimes clients have to try 10-20 times
to get a connection, some on the first try do, thats confusing.. and
they mantain conections opened (nobody wants to loose it). Well, look at
some of my outputs:

I don't know a place to begin. What is high and what is low.. I know
(and I want to learn more) that these topics is for people that
understands better about TCP/IP and firewalling, but people wants
something more like 'basics', and then jump to something more
sofisticated.. That's why I asked for a section on howto or faq talking
about this, covering o.s. too, I'm sure that lots of people will enjoy it..
Thanks for your support.
