5/13 Suppose I send something to localhost or the local name. Will the
computer be smart enough to not route stuff on the interface card?
I've noticed that I'm getting 92Mbps on FTP across my LAN, but
a whopping 200Mbps using localhost name (I have a 100Mbps LAN). I'm
wondering how that could happen.
\_ Do the LEDs on your hub or the card actually blink? I guess your
monitor software is just not smart enough to connect to the right
layer.
\- normally lopback stuff doesnt hit the wire. however in
freebsd if memory server, you can change something so that
traffic for the locahost's ip does get put on the net.
i dont have to to lookup details now but if you cant figure
this out i might be able to help more later. --psb
\_ Well the computer's in the lab (E450) so I can't check. I got
the throughput using my home brewed network hogger. I've
verified 1 process =~ 92Mbps, and 2 process =~ 89Mbps, etc...
\_ why lower throughput with 2 processes? Broadcast conflict?
\_ Normally yes - look at netstat -rn and notice that localhost has
a special route that goes through the loopback device instead of
your ethernet device and has a much higher MTU. |
