      @Tom-Elliott So I moved an SSD from a slow machine to a machine that is running at full speed, and I can confirm that I get full speed out of the drive, so that rules that out.

      Can someone tell me where I can enable/adjust logging levels for the kernel? I couldn’t seem to find it in the web gui.

      Thanks!

        @Tom-Elliott @JJ-Fullmer Never mind, I found the logging levels. So now that I have the level maxed, where do I find the logs? Is that still in the web gui somewhere?

        Thanks!

          @Quintin-Giesbrecht It’s been a while since I’ve had to mess with it, if memory serves it may show in the output of the imaging itself. You might need to do a deploy in debug mode on a fast/normal speed machine and then a slow one and compare what you see.

          You may also find some logs in the log viewer of fog within the fog configuration page. Where the logs are on the server depend on your fog version and your OS version.

          Like for me on Rocky 9 with Fog 1.6 and using apache with php 8 the log with the most information is /var/log/php-fpm/www-error.log but I don’t believe kernel level stuff will output there.

          Have you tried the FogApi powershell module? It's pretty cool IMHO

            Greetings.
            Same issue here with LENOVO Neo 50s Gen 5 Desktop series.
            Every other model works fine, but not this one.
            Capture at 10 Gib/min, but deploy a 600 Mib/min.
            The network port is 1 gbit/s during both opération.

            Updated fog to the latest 1.5.1660, same issue, testing the beta Linux kernel 6.12.25 / Buildroot 2025.02.0 : same.

            Realy stuck here, i’m waiting 200 others same PC on september 2025.

            We tested on 3 differents FOG server in different location : same issues.

            Thanks for any help.

              @olivier-bonnici If you have time to test, I have an idea what maybe causing this. I just saw a video on hacking a chromebox (seemingly unrelated), and they had a similar issue with downloads being unnaturally slow but uploads were OK.

              It came down to the energy efficient ethernet built into the realtek nic.

              What I want you to do this this:

              1. schedule another deployment to this hardware, before you hit the schedule task button tick the debug checkbox then schedule the task.
              2. PXE boot the target computer, it should go right into imaging, well it should drop you to a linux command prompt after several screens of text.
              3. At the linux command prompt, we need to find the name of the ethernet adapter device. Issue the following command ip a s . Look in the list for the network device that has an IP address. Write down that name for the next stel.
              4. Use the linux tool ethtool to disable ‘eee’ on the network adapter, in this case the ethernet adapter name is eno0 yours might be different, fix accordingly ethtool --set-eee eno0 eee off
              5. On success of setting green ethernet to off lets start the imaging process. Key in fog and press enter. This will place you in single step mode. You will need to press enter at each breakpoint in the code but you will be able to see the partclone screen to see if the speed has improved.

              I don’t know specifically if this is your issue but its worth a shot. If it does work we can do a few things to make this a forever change, but first we need to find out if it works or not.

              Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

                @george1421 Thank you for your help.
                When i enter the eee off command, the system tells me it is already disabled.
                I try downloading an image, but same low speed at 600 Mib/min.

                I have changed the nvme drive by an old SSD : same low speed ><.

                  @olivier-bonnici Edit : Works better with an older Kernel !
                  Deploy with kernel 5.68 from october 2022 is running at 3-4 Gbits/min.

                    @Quintin-Giesbrecht Hello ! A friend of mine have added the correct driver into the bzimage file.
                    I can get 12 Gib/min with this modified kernel.

                      @olivier-bonnici Could you please provide this image, as it will help make my life easier. Also could you provide it to the devs so they can integrate it into FOS?

                        Can you explain this in a bit more detail? Lets see if we can help everyone do better, please.

                            @george1421 I tell me i recompile the kernel using https://kernel.org/ and the fog procedure.
