comment How do I calculate the ethernet NIC-to-NIC time to send a MTU packet (1500 bytes)? (OS-excluded)
"is is dependent on the hardware" - YES, it is dependent on the NIC. So maybe all you have to do is take the ethernet SPEED, multiply by 2 (two nics) and that's it.

The OS is excluded from the question. I know there is a way to calculate the Nic-to-Nic time.

I will have to double-check because I was under the impression that you need a send operation and a receive operation, therefore there is time spent on EACH NIC on two different operations and each one take time.

I think you are wrong. You have to multiply this by 2, one for each NIC (i.e. the one sending and the one receiving). No?

I am debating if I should do this over loopback and forget about wiretime for now since it will vary over 1Gbit, 10Gbit and Infiniband. Problem is: I will be sharing CPU power with 2 process, and I only have one quad-core chip. Maybe pinning each process to its own core will be enough but not sure.

You mean use the fastest ethernet card available? What is the fastest one these days?

comment What buffer size should I use to maximize disk I/O bandwidth? (16Kb, 32Kb, 64Kb, etc.)
Thanks to Tonny. For the rest you should work on your attitude towards hardware noobs. I am not ashamed of saying and don't know that stuff, i guess that's why I am here, right?
