    Question Multiple Data Streams - Lan Speed Test v3.0.0 Beta

    How would one calculate the total aggregate throughput when there are multiple data streams? Would you simply just need to multiply the ending result by the number of data streams? If so, would it be possible (perhaps in the drop down box at the very top) to display this information?

    doug.

    The more I think about it, the more I don't think it's possible for the end user to accurately calculate the total aggregate throughput at any one time or overall. For one, we are given mean/average result values. We would need the data from each stream's packet to calculate the overall aggregate total throughput. An average/mean of a group of average/mean values doesn't necessarily give you the same value as taking all the values individually and dividing it by the total number of packets (number of streams x number of packets for each stream). Am I way off base here?

    Doug,

    Good, I got you thinking too! There was a lot of thought, trial & error, testing, and code re-writes into this routine (multiple streams) as I was trying to display the most relevent information while trying to keep LAN Speed Test as simple to use as it's become well known for.

    In a nutshell, here's how it works...

    1) Each stream is testing at the same time
    2) Each Stream comes back with total time taken, fastest packet, slowest packet
    3) Now, the totals get added up and averaged to display the average, high, and low for each stream and even each packet

    Only the total times, fastest times, and slowest times are stored. Averages are always calculated at time of display - so they don't become skewed. With this information, I can pretty much calculate whatever we want. Is there a better way to display the results? I'm open to suggestions.

    -Pete

    Doug,

    I have re-vamped the streaming tests and results. Now, it measures Maximum throughput. I hope to have it ready for you to test in a day or two.

    Pete,

    I am sorry for not responding earlier. I did not realize that you had responded to my post.

    We envisioned seeing an aggregate throughput value in addition to the individual stream values. We really didn't know where you might add, or how you would determine, the values in the Beta version we were testing. We just knew that we needed to some how determine those values.

    We agree that you should keep LST simple. We hope you were able to keep it simple after this latest Beta version. We will test it soon and provide you feedback.

    That said, we would really like to see a graphical representation of what is going on. We don't need to see it real time, nor inside LST. Would it be possible to be able to save the values in a comma delimited format so we could graph the data in Excel? Again, we don't want any of the data points/values to be displayed, just perhaps kept in memory so it could saved to a file after the current test has completed.

    Does this request make sense?

    FYI, the main reason that we don't necessarily need to see the values in graphical format during run-time is because we don't want that logic to adversely affect the timing logic in the app. We realize that you have gone to great lengths to ensure the throughput is very accurately calculated. You might think about adding it to the next release (v4). That would be another good $5 spent.

    Doug,

    What about running LST from the command line with auto repeat and log the results (The log is a .csv file with all test results compatible with opening up in excel or sql)? Is that what you are requesting?

    We have not looked into the command line functionality. From what you are saying it should meet our needs. If it doesn't then I'll let you know.

    We tested the latest Beta version. It is working great. With one stream we only utilize 40 - 50% of our gigabit network cards' bandwidth. With 4 or more streams we utilize 99% and achieve 950 -1015 Mbps throughput!

    Why is average and minimum disabled in multiple stream mode? We would really like to see those values as well.

    Yes, the new command line functionality is very powerful! Thanks for the Simultaneous results. I pm'd you on the rest of the details.

    Aren't the read speeds a little high?

    FYI, I switch where LST Server and LST run the results are exactly the opposite (the write speeds are 1000+ Mbps and the read speeds are 550+ Mbps).

    I will try to test multiple PCs running LST to one PC running LST Server tomorrow. Right now I am the only one in the office.

    Doug,

    You need to update your LST Server to version 1.3. Scott discovered some major differences in testing between the older LST v1.1 and the newer LST v1.2. I looked through the code and found a nasty bug in LST v1.2 receive routine that would slow down LAN Speed Test writes. It's fixed and release as LST v1.3 and is available at www.totusoft.com.

    -Pete
