15. gani driver for Realtek rtl8169 rtl8110 rtl8168 rtl8101 PCI/PCI-Express GbE chipset
Tested OS version:
Solaris9 12/02 x86, solaris10 3/05 x86, solaris nevada b48.
730Mbps for tx and 830Mbps for rx with 33MHz/32bit PCI bus and Athlon2800+.
Tested chips (PCI/PCI-e card product):
RTL8169S-32 (Planex Communications GN-1200TC)
RTL8169S-32 (Corega CG-LAPCIGT)
RTL8168B (realtek demo card, only supported by gani-2.0.0 or later)
RTL8101E (realtek demo card, only supported by gani-2.0.0 or later)
RTL8169SC (realtek demo card, only supported by gani-2.0.0 or later)
The performance "reported" looks impressive - 700-800 Mb/Sec+ rates.
Just two performance data points, I'd need to know more about how both tests were made, both Peter's and the quoted website before I could make any decision.
