Very Computer

I have a couple of HP Netservers running Solaris 2.6.  I am using SMC
9232 10/100 EISA Ethernet cards.  Solaris provides drivers for these
cards but I am getting very slow transfer rates, about 600 to 650
K/sec.  I recall in 2.51 on the Sparc platform I had to force the HME
card into Full duplex mode.
Does anyone have experience with these cards and Solaris 2.6 for Intel.
If so any advice would be appreciated.

Thanks
