I run the same card in two systems on a Cisco catalyst 5500 switch.

Either will get 8.5-9 MB/sec download.  One will get 8.5Mb/sec upload, the
other only about 1.1MB.sec upload.  (In all cases using a Solaris remote host
and transferring a 20Mb file of '\0's from /tmp to /dev/null in binary mode.
Links are 100FD autonegotiated.  Both PCs are HP Vectra VLs but I can't easily
verify how identical the hardware actually is.)

Both are running 4-Stable, the fast one from 4.3BETA, the slow one from last 
week (but I suspect it is more a case of hardware differences as the slow 
machine is older and has always been slow).

(Non-verbose) dmesg for the slow machine:
xl0: <3Com 3c905B-TX Fast Etherlink XL> port 0xfc00-0xfc7f mem 0xfedff800-0xfedff87f irq 9 at device 14.0 on pci0
xl0: Ethernet address: 00:10:5a:a1:7c:7a
miibus0: <MII bus> on xl0
xlphy0: <3Com internal media interface> on miibus0
xlphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto

and the fast one:
xl0: <3Com 3c905B-TX Fast Etherlink XL> port 0xfc00-0xfc7f mem 0xfedffc00-0xfedffc7f irq 10 at device 13.0 on pci0
xl0: Ethernet address: 00:10:5a:a1:7c:78
miibus0: <MII bus> on xl0
xlphy0: <3Com internal media interface> on miibus0
xlphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto

I am willing to help out anyone with ideas about this.

Greg.
