Hi Jeff,

I made some speedtests with another similiar freebsd-product and a VIA C3 Nehemia 1GHz with 
2 ViaRhine 100mbit-cards and two Client with 100mbit 3coms directly connected to it.
I used netio to measure the speed. Clients directly connected to a switch without the firewall
in between measured about 89mbit/s. With the firewall in between (configured like a m0n0wall 
with default settings doing NAT) I got about 86-87mbit/s. CPU was running at about 75% during 
the tests. Did several testruns. No noticable delay with that platform.

Since the tests were done with a freebsd 6 version and m0n0 runs on freebsd 4.11 networkperformance
of a m0n0 on this hardwareplatform should even be better.

Betreff: [m0n0wall] Speed/Overhead Question

Hi there-
I've set up a m0n0wall, and haven't used it much, but
it seems like it should do everything I would need,
but my question has to do with the speed.  

Does anyone know how much overhead m0n0wall uses?  For
example, using m0n0wall as a bridge, how does
throughput compare to having a simple switch or hub
instead (with no m0n0wall at all)? 

I would think
there has to be some overhead if m0n0wall is examining
each packet that goes trhough.  I realize an exact
answer would depend on the specific hardware used to
run m0n0wall, but I would like to know any ballpark
answer anyone might have to help, or if they know what
hardware that would help too.  For example, if I am
using m0n0wall with 100Mbps ethernet cards, and with
regular hardware hubs/switches I get 60Mbps
throughput, I would like to see monowall 59Mbps or
58Mbps throughput, as opposed to 50Mbps or 10Mbps,

I've looked around through this list, the FAQ, and the
'net and been unable to find an answer. But it would
seem to me that this would be a concern for others as
well, useful to know.
