I have two machines,
x486 486-66, 20MB, 1GB, Intel Etherexpress
486-clone FreeBSD 2.1.0 from CDROM (and WINDOZE NT)
tinb 486-50, 20MB, 200MB, NE2000-ish interface
Texas Instruments 4000 Notebook (486-DX2-50)
Local ethernet, no other nodes.
I first noticed the strange behavior when I attempted to install
FreeBSD on the TI NOtebook. Boot the floppies was OK. Install
seemed to start OK. Then, I noticed the network traffic speed
was on the order of a few KB/sec. Sometines, there were 7 minute
delays between network transactions. Well, as expected, things
finally timed-out.
After a couple of tries, in SHEER desperation, I booted WINNT 3.51.
I retried the install. WHOA!! things were very fast! The network
was running at what I consider normal speeds for a 10Mbit link.
The install completed successfully. The TI Notebook seems very much
faster with FreeBSD than WINDOZE! I am happy with that.
What bothers me is the difference in speed between FreeBSD-FTP and
WINNT-FTP on the x486 machine. Since the machine behaved differently
with the two OS's, I assume it may be my network setup for FreeBSD.
I tested ftp after completing the installation and found:
ftp tinb/FreeBSD -> x486/FreeBSD ~4KB/sec
ftp tinb/FreeBSD -> x486/WINNT ~1.6e3 KB/sec.
I am using private IP's, x486=192.168.1.1 and tinb=192.168.1.2
both with netmask of 0xfffffc00. Route tables look OK. The only
difference I have found between x486 and tinb is in ifconfig.
on x486, ifconfig ix0 returns:
ix0: flags=63<...> mtu 1500 inet . netmask . broadcast . ether .
on tinb, ifconfig ed1 returns:
ed1: flags=8863<...> mtu 1500 inet . netmask . broadcast . ether .
where . indicates that the values are the same or differ by IP/HW.
The flags SIMPLEX and MULTICAST are set on tinb, but, not on x486.
Can this be the problem? I cannot seem to locate a mechanism to
turn off these flags. Can anyone help?
Has anyone experienced this slow network behavior?
thanks,
tomdean
