NIC performance

[wajed]

I have a NIC in my notebook and I would like to see how fast it is, how can I do that?

I tried to use Sisoft Sandra, but it gave me 2MB/s! I think it is wrong.

So, how can I measure bandwidth and latency?

It is a Realtek PCIe GBE network card, by the way.

Go to PC A and run netcps.exe -s (server mode) http://www.netchain.com/netcps/
Go to PC B and run netcps.exe xxx.xxx.xxx.xxx where xxx is the ip of PC A

The problem is that this seems to depend on PC A, PC B, and the connector (the switch). Wrong?

Correct. But what good is a NIC if it isnt communicating with another host?

I wanted to know the speed of the NIC of my PC itself.

Using netcps didn't give much better result than Sisoft Sandra. I got 1MB/s peak. There is still the possibility that the network itself (for example, PC B) is slow and that Sisoft Sandra is wrong.

Anyway, assuming it's primarily my NIC, how can I reach Gigabit in my notebook?
It has Firewire 1394, USB2, expressCard slot, and a (replaceable) wireless card.

If you know the model of a network card you can find what is rating is.

If you want to know how actauly it performs you have to measure its traffic with other computer.

Otherwise it is like asking how fast is an elevator that does not move and stays on the same floor.

These numbers are discouraging! But the good thing is they are a bit out-dated probably (2004, and updated 2006 - it is 2011 now)

NICs are Not Video cards.

The capacity the same type pf of the cards did not change in time.

Whatever a Giga card could do than, it does Now.

He mentioned OSes being limitations. OS changed very much in 5 years. CPUs also are faster now. HDDs are much faster, not to mention SSDs didn't even exist.


"
Wireless 802.11g Yields 16-22 Mb/sec. (2 - 2.8 MB/sec.)
Wireless 802.11g (Super/Booster etc.) Yields 28-38 Mb/sec. (3 - 4 MB/sec.)
Wireless pre 802.11n (MIMO) Yields x2 - x4 than 802.11g at close proximity, more gain might be achieved at distances above 60'."
I think wireless cards now reach 450Mbps.

Sure it "connects" at that, but thinking you are getting that kind of performance is living in fantasy land
