 Slow network/disk when "getting" files

I have a Pentium II machine with 80MB RAM, 2.5 GB Seagate IDE hard disk and
a 100BT Card (3Com 3C905 TX) running FreeBSD 2.2.5.  I noticed when I
grabbed a largish file via an ftp "get" I was only getting around 125
kb/second - the remote machine is also on 100BT and the network was not
busy.  I was expecting quite a bit faster than this so I decided to "put"
the file back via ftp and found that the speed increased dramatically (to
1.4 MB/second - over 10 times faster).

Obviously there is something wrong with either the network or the disk
setup.  Does anyone know if there are problems with the network drivers
or if there are some special parameters I need to tweak to improve this
performance before I start fiddling aroudn with different cards/disks/setups?

Thanks

Hmmm.  Have you tried the same test with the Intel EtherExpress Pro 100B
or DEC (clone) DC2114x based NICs?  I don't believe that the 3C905
is being used very efficiently by the current driver and there are plans
afoot to fix this, but my own tests with the Pro 100B show xfers of at
least 4MB/sec and as high as 7.6MB/sec between similarly configured
FreeBSD machines (PII/PPro) with 100BTX connectivity through a switch.

Hi David:
Lan Driver bug maybe cause the problem .May you e-mail  the driver source
file and setup file to me. I am a  lan Driver programmer and  maybe  I  can
 verify if the driver bug.
