Hi!

I am not sure what is the best zone for this question.

I want to measure throughput of Gigabit Ethernet (UDP).  I do not want to use an external tool.

1) If I connect 2 Windows PCs directly, and try to transmit "tons of data in one direction", what is maximal expected throuput (Using Fullduplex gigabit Ethernet) ?
2) If I connect 2 Windows PCs through a "good gigabit Ethernet switch", and try to transmit "tons of data in one directions", what is maximal expected throuput (Using Fullduplex gigabit Ethernet) ?
3) If I connect 2 Windows PCs directly, and try to transmit "tons of data in both directions", what is maximal expected throuput (Using Fullduplex gigabit Ethernet) ?
4) If I connect 2 Windows PCs through a "good gigabit Ethernet switch", and try to transmit "tons of data in both directions", what is maximal expected throuput (Using Fullduplex gigabit Ethernet) ?

Is there some where a C/C++ code which gives the answer for the above questions ?
Later I would like to run the same code on 100 Mbit Fullduplex Ethernet, and 10 Gbit Fullduplex Ethernet.
Later I want to compare the results to Infiniband.

I am not interested in precise result, just Tipical throuput.


This question is continuing a previous question. See Prev_Question  for more details..


Thanks

You might want to take a look at http://www.totusoft.com/lanspeed1.html before you write your own.  I had seen this before and forgot about it.  I just downloaded it and I'm going to try it myself.  I'll let you know if there are problems.

I am "on the door". I'll test it after the weekend.

http://www.totusoft.com/lanspeed1.html is a very interesting program.  It doesn't require installation, just runs from the EXE.  It writes a file to a destination and then reads it back while measuring the throughput both directions.  That's probably what you want because that will include the file system and anti-virus and any other system overhead in the process.  I noticed that sometimes it would slow way down.  Also that it makes a difference which computer initiates the test.  On one computer I got 5MBytes p/s upload and 10MBytes p/s download.  If I measured from the other computer (reversed the path), I got 9MBytes p/s upload and 10MBytes p/s download.

Hi,

I had not tested the program yet (I am soon going to do it).
I wonder if there is a code which I can read/change ?

I don't think they offer code because they have a commercial version also.  I'd try the program first since it takes less than 5 minutes to download it and use it.  Could save you a lot of time.
