Hi friends,
I'm experiencing really poor network performance via the Realtek 8101E (re)
Ethernet card on my HP Mini 110. Using the default setting of tcpbench
I'm getting an average Mbps of 0.172 versus a compatible machine (Asus
Eee PC (alc)) where I'm getting 92.690 Mbps.
I suspect this class of card might just not be supported very well
or perhaps is just a big smelly meatball but I figured I'd ask in case
someone has run into similar problems with this NIC. Any suggestions?
