ok, added to the todo list ;)
and view your firewall configuration on both machines very
carefully. What are the specifications on the Mac?
the Mac is a dual G5 2GHz, 1.5 GB RAM, 160 GB SATA HDD, it uses ipfw
for internet sharing purposes between its eth and its wifi interfaces:
# ipfw list
00010 divert 8668 ip from any to any via en0
65535 allow ip from any to any
the FreeBSD has 1 GB DDR2 ECC, 2 250GB SATA II HDD (but motherboard
controler is on SATA I) and uses pf:
# pfctl -s all
TRANSLATION RULES:
nat on fxp0 inet from 192.168.0.0/24 to any -> (fxp0) round-robin
FILTER RULES:
scrub in all fragment reassemble
block return all
block return in log quick proto tcp from <sshscan> to any port = ssh
pass quick on lo0 all
[ bunch of block in/out and pass in rules applying only on fxp0, the
external IF ]
pass in inet proto icmp all icmp-type echoreq keep state
pass in on em0 inet from 192.168.0.0/24 to any keep state
pass out on em0 inet from any to 192.168.0.0/24 keep state
[ few pass out rules applying only on fxp0, the external IF ]
No queue in use
I averaged 7.5MB/s with sftp and the peak speed on the HTTP
transfer was only 7.1MB/s with Apache 2.2.
scp gives me 5.6 MB/s from the Mac to the FreeBSD, but HTTP gives me
20-21 MB/s from the mac (apache 1.3) to the freebsd.
Arne's nc trick (server: nc -l 1234 > /dev/null ; client: dd if=/dev/
zero bs=1m | nc serverIP 1234) gives me at best 23.7 MB/s with
freebsd as server. About the same with the mac as server.
Everything else is still to be tested.
thanks,
