Hi,

New (small) tool to test your network adapter speed.
Posting here first to see if program works like it should...

Now version 1.3-BETA
Download:

Results for my gigabit adapter Marvel yukon are 87Mbits/s and for my Realtek 8169 are 326Mbits/s.

NF4 -> Intel Pro1000XT 543.9Mbit/s
Intel Pro1000XT -> NF4 355.5Mbit/s

Just a couple things that would be nice:
1- Selectable text or logging for comparing multiple runs.
2- Option to set DF flag for MTU/Jumbo frame testing.

Thanks for all your hard work Bart!

DF flag???

Bart.

Broadcom NetXtreme Gigabit Ethernet, running at 100 Mbps.
==> 11.2 MByte (89.8MBit) per second.

At first I didn't see the [>>] button, maybe change it into [Adapter info] ?
Adapter info is okay, but:
- lease obtained shoud be in human readable form
- lacks physical address
- lacks actual network speed

Tool does also work under in BartPE under VMware, but obviously has limited use there since it talks to VMware gateway (i.e. not across physical network).

Erik.

Is the Yukon connected to a 100Mbit/s and the 8169 connected to a 1000Mbit/s network?

Bart.




Got it.
Bart.

Bart,
DF - Don't Fragment packets. (like ping -f )

-timotl

If you like this, you should also check out QCheck and endpoint services from Ixia (formerly by NetIQ). I posted plugins for these today.

Both are connected to 1Gb/s network.

Ah! Yes I noticed that large packet arived fragmented, will check...

Regards,
Bart.




The yukon at 87mbit/s is performing a bit slow...

Bart.

v1.2-BETA

- Removed IP selection control, program now searches for a free IP address and uses that.
- Changed the adapter "info" button and added some more values.
- Added a "copy to clipboard" button.
- Added a "stop" button.

Could not find a way to set the "don't fragment" IP flag, but will keep searching...

Bart.

Hi all,

Version 1.3-BETA, going fast...

1.2 used a free IP address and a made up a mac address (01-02-03-04-05- 06) to
send packets. But this can makes a network switch really crazy, and packets
will get broadcasted over all ports, not nice.
Fixed this, now first checking if the gateway address is valid and if not
scanning the IP range for a valid IP address to use in test. This will send
the packets to only one host (and one switch port) and not to all!

Just curious, why remove manual IP selection?
I like being able to abuse, er direct traffic to a specific IP.
(mixed 1Gb and 100Mb network)

connected to a 100Mbit network

Linsys LNE100TX 10.3MByte (82.8MBit) per second
NetGear FA30TX 9.3MByte (74.2MBit)

Just to keep the program as simple as possible.

Adapter 2 is not detected.
Cheers Kutte

Hi,

Can you see why it is not detected?
I use GetAdaptersInfo function to get the adapter...

What adapter is it and what OS?

Bart.

Thanks for a useful tool

Results for RLT8139 - Average sending speed is 11MByte (88MBit) per second.

Results for SiS 900 PCI card - Average sending speed is 11MByte (88.2MBit) per second.

I have two NIC's on my PC. The RTL8139 is manually configured and usually enabled and working.

The SiS is automatically configured and generally disabled and often disconnected (I use it for setting up and testing routers). When I tried NicSpeed on the SiS it failed because the SiS was disabled. After I enabled the SiS NicSpeed again reported failure. Clearly NicSpeed did not get the updated SiS properties. Closing and re-launching NicSpeed forced NicSpeed to refresh. It worked and gave the results above.

Could NicSpeed have a button to refresh the Nic properties?

i also get slow on my marvell yukon 88E8053 gigabit adapter.

Average sending speed is 11.4MByte (91.2MBit) per second.

Can't test GB adapters... my Gateway is a router with a 10/100 port so speed will always be limited to 100mb.

Yeah it would be nice to set the destination .. for testing ..
the gateway isn't allways the fastest connection

I dont think it matters how fast the destination computer can receive the packets. It only matters how fast the adaptor can spit the udp packets out onto the network.

ok .. so my computer 1gb .. 1gb switch .. gateway (used for testing) 100mbit ..
how fast do you think the test will be..

350-550Mbit?

ok .. if you say so ..
going to check it friday .. when i'm back at the office

thank you !!!

Thanks for this tiny tool.

My Internet card result is as under:
