    Hi all, Is this still the latest version? I have ver 4.06??

    Good to see there are still people here.

    We are now on what is called NBN (national Broadband) and the speeds are fair, 100mbps down and 40mbps up, better than before

    https://www.speedguide.net/articles/...n-history-5811

    - Optimizer is now aware of, reads and displays the current TCP/IP settings "template".
    - Updated Congestion Control Provider command, added "CUBIC" and "NewReno" algorithms introduced with Windows 10 Creators Update.
    - Changed RSS (Receive-Side Scaling) and RSC (Receive Segment Coalescing) settings to be applied globally.
    - Fixed Chimney Offload command (made change global) and program now reads setting on startup.
    - Changed default to modify all network adapters.
    - Removed obsolete DCA (Direct Cache Access) setting.
    - Program now reads most settings on startup.

    The updated online documentation and revision history are available here:
    TCP Optimizer Documentation and revisions

    Thanks for still developing this great tool

    Is ctcp still the best option to chose or are the "newly" added ones better? I've read through the documentation but i don't think it was listen (sorry if it missed it).

    CUBIC is now the default in Windows 10 (since the April 2018 v1803 update).
    I would like to think Microsoft have made this change for a good reason.
    I have switched between CTCP and CUBIC to test but cannot see any noticeable difference.
    Very interested to hear from Philip, and any other experts in this area, as to whether Microsoft's change to CUBIC makes sense.

    The change to CUBIC makes sense in general. Newer Linux kernels use CUBIC as the default. I am just worried a bit about the MS implementation, and users have different builds with various support, that is why we haven't moved on to recommend it yet in the program's "optimal" settings yet.

    By all means try it. In theory it should be better than New Reno for sure, and maybe slightly better than CTCP. The only disadvantage (if it can be called that) is it creates somewhat larger TCP buffers with high-speed/latency transfers. It should provide a bit better throughput and a more stable connection if the line is completely saturated. I don't see any advantage over CTCP for games/lateny (it provides a bit more equal/"fair" buffer across different rtt connections in theory), but it should work better for pure throughput.

    I have added more info on it to the TCP Optimizer documentation.

    Is it possible that your Network Adapter (or CPU/Motherboard) doesn't support them? I have just tested it on two v.1803 machines and it shows both RSS and RSC.

    I'm sure it is. I can enable or disable it but TCP Optimizer just don't show the current value

    I'd like a bit more info if you don't mind:
    Was it any different with the previous version of the Optimizer?
    Are you starting the TCP Optimizer as an Administrator?
    What is your Network Adapter brand/model?
    Does it show selected when the TCP Optimizer starts?

    Thanks

    I always run TCP Optimizer as an administrator. In the past I was using Win7 pro in the same computer and TCP Optimizer showed all options fine but since I changed to win10 the RSS and RSC value is missing even with an older tcp optimizer version. Now i'm in a fresh win 10 1803 home installation in the same hardware setup as always. The network adapter is a Realtek RTL8111DL

    Great tool, super helpful.

    Some feedback:
    I'm using Win 10 64bit Education Edition, Build: 17134 6.3
    My NIC is an Intel I 219-V (Asus Ranger VIII mobo)
    I use intel's driver not microsoft's

    I can't set the PPPOE checkbox in optimal mode.
    Also: it would be nice if the mtu/latency tab could also check for pppoe fragmentation (that probably needs a running server though, unlike ping)

    Some values aren't applied correctly, so I visited my driver's settings to change them manually (except enc):
    Receive-Side Scaling
    R.Segment Coalescing (couldn't find that in the driver's settings either)
    Large Send Offload

    ECN capability wasn't turned on correctly by the tool, I had to do it manually over the command-line (using netsh)
    I used enabled instead of default now, since I'm unsure how to set it to default


    Some values the software can't read out:
    Receive-Side-Scaling
    R.Segment Coalescing

    Regards

    Hello Djfe, thank you for the feedback.

    I just tested with the latest version of the optimizer (4.0.7), and Windows 10 Pro build 17134.6.3 and Intel I219-V (Asus Z170 Sabertooth MoBo).
    The software seems to be able to read/change the RSC and RSS values correctly (just restarted the TCP Optimizer program).

    Are you using the latest version of the program? There are sometimes variations between the different Windows editions, but we seem to be using very similar versions, other than the Pro vs. Educational, and the NIC driver.

    I'm using 4.0.7

    This is how it looks like, when I start the tool with admin rights:


    I'm using Intel's driver version 12.17.8.7 from 09/29/2017

    If I click optimal and save and restart, then those two fields still stay empty

    Interesting.. Works with Intel driver v. 12.13.17.7 (8/13/2015), same Windows build



    Is it possible that you have more than one Network adapter, and the TCP Optimizer is reading/showing the first one, which is not capable of setting those parameters? If you start the Windows PowerShell, and execute the following commands do you see more than one Network adapter? -->


    Get-NetAdapter

    netsh int ipv4 show subinterface

    Get-NetAdapterRss -Name *

    Get-NetAdapterLso -Name *
