The only thing I don't like about the myri10ge cards is that they lack VLAN offloading in hardware.

I haven't done any comparisons with other vendor offerings, but I can highly recommend the Myricom PCI-Express (8x) 10-GigE NICs. They only cost about $900 and can do full unidirectional 10-GigE line rate. And as a 10-GigE router, they can do full bidirectional 10-GigE line rate IP forwarding. Note the choice of system/motherboard/CPU is as important as the choice of NIC in achieving maximum performance. Sample nuttcp test: chance7 -> chance9 10-second TCP test: [EMAIL PROTECTED] ~]# nuttcp -w10m 192.168.88.16 11817.8125 MB / 10.00 sec = 9909.8073 Mbps 100 %TX 71 %RX The system specs are: Tyan Thunder K8WE S2895ANRF motherboard with Nvidia nForce Professional 2200+2050 chipset, 2 AMD Opteron 254 2.8 GHz CPUs, 4 GB PC3200 ECC REG-DDR 400 memory, and 2 PCI-Express x16 slots (2 buses). The systems are running a 2.6.20.7 kernel. Perhaps others can share their experiences with 10-GigE NICs. -Bill - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

In search of 10gbps cards/shootout in Linux?
There are various agencies/educational institutions doing testing but was curious if anyone has 'found' a 10 gigabit card shootout measuring the performance between 10 gigabit cards on the 2.6 kernel? Most of the benchmarks are from the vendors themselves Intel/etc-- was wondering if there were any vendor-independent benchmarks out there? Until switches come down in price, 10gbps will be most relegated to business/research use and therefore such benchmarks probably will be hard to come by but I thought I'd ask..
