I just got a new cable modem for my home network, so I set up one machine with FreeBSD 3.4 as a gateway running ipfw with open
policy, and IP aliasing with natd. I am getting a big drop in throughput after implemented this. Originally, my peer Win98 computer
that was connected directly to the cable modem was reading 35 Kb/sec download rate from ftp.freebsd.org site. After going through my
Gateway the rate dropped to 8-10 Kb/sec. I went through the mailing list archives and the only thing I could find was to avoid cheap
NE2000 clone cards which I am currently using. However, I can't believe that cards alone would be the cause for this drop in
throughput. What could I do to remedy this?
I am running FreeBSD 3.4 as a gateway
Pentium 200
2 GB IDE drive
32 MB RAM
Cable Modem is Plugged into ISA NE2000 clone
Another LinkSYS PCI NE2000 connects this machine to my network hub
I am running cache only DNS on this machine
I have 3 other computers with various OS's connected to my hub.
I am also running lots of services and apps on this gateway including Apache, mysql, NFS server, SAMBA, X windows on and off, etc.
My question is:
1) How can I get the highest throughput via this gateway?
2) Should I strip this machine of all extra apps and services except IP aliasing and IPFW and DNS?
3) Would adding more RAM make much difference?
4) Are my network cards sufficient for providing high throughput for 2 simultaneous Internet users?
5) Am I missing anything here?
Thanks,
Alex
