  1. I had this a while ago and couldn't get anywhere near bear metal performance. You can get quite complex with this and start looking into IOthread pinning to help, but there's only so much you can do with a virtual disk controller vs a hardware one. You'll probably notice a bit of a difference if you use the emulatorpin option to take the workload off CPU0 (which will be competing with unraid stuff). if you have a few cores to spare, give it a hyperthreaded pair (one that you're not already using in the VM). In the end I got a PCIe riser for an NVME, and passed that through to the VM. You get about 90% of the way there performance wise compared to bare metal as the controller is part of the NVME itself. Good luck.
  2. I have read reports that the Vega iGPU can be used for transcoding in the plex forums, however with it being quite a niche situation where you have a plex server, AND one of the very few CPUs with the vega iGPU, reports are few and far between. However, to be in a position to test, and to be able to talk with people in the plex forum on how to get it working, I need to be able to expose it to my docker container! Also like youve said, its not just plex which could make use of the iGPU.
  3. I'm struggling to see any downside to seeing this get included. Especially if its only enabled by a boot option?
  4. Ive dropped the £ on the memory to get these sold so they're not gathering dust. 32GB DDR3 PC3-12800R 8x M393B5170GB0-CK0 4GB PC3-12800R £60 32GB DDR3 PC3-8500R 8X M393B5170EH1-CF8 4GB PC3-8500R £75 All 64GB for £130
  5. So docker images can make use of iGPU transcoding.
  6. Is it possible to enable the AMD APU iGPU Drivers in this build somehow? @eschultz
  7. Please could the drivers for the Ryzen APUs be added. I believe the prerequisite kernel version is 4.15, and we're on 4.19.33 on the latest RC. It was mentioned here by @eschultz, but ive never seen any mention of it getting implemented, or if it has been, how to enable it: Id like to use the GPU to aid in transcoding in my plex docker (which while undocumented on the plex side, it does apparently work). Even if it wasn't enabled by default, and required adding boot code(s) in syslinux, or a modprobe command in the go file, id be happy! Or even if there was documentation somewhere on creating a custom kernel with the driver enabled? The 2400G is a little workhorse, and adding GPU transcoding would make it a pretty amazing!
  8. Having an upgrade so I'm selling my dual Xeon setup... All items are working great and haven't been overclocked. I will post internationally, but please bear in mind that international postage from the UK is expensive!

  9. QEMU 4.0 RC0 has been released - https://www.qemu.org/download/#source And a nice specific mention in the changelog to things discussed in this thread (https://wiki.qemu.org/ChangeLog/4.0): Now that these changes are standard with the Q35 machinetype in 4.0, I think this could also be an additional argument against potentially forcing Windows based VMs to the i440fx machine type if this brings things into performance parity? If @limetech could throw this into the next RC for people to test out, that would be much appreciated!
  10. It was me I think the current behaviour in the UI is perfect. Pick an OS, and the sensible, least hassle settings are there for you to use. I dont think options to change the machine type should be removed. At worse, they could possibly be hidden behind an "advanced" switch (which i think currently flips between the form and the xml), then having another tab to view xml instead?... I know there's a balance to be found to accommodate all levels of unraid users here, and i dont envy the UI decisions to try and keep everyone happy! It is worth pointing out that its documented the drivers DO behave differently based on what PCIe link speed they detect, and personally i get better performance numbers, and prefer running a Q35 based VM... I think the long term fix for this is to either allow the option to run modules such as QEMU, libvirt, docker from the master branch, and allow them to be updated independently to the OS, or to have "bleeding edge" builds where these modules are compiled from master. Easier for me to say, than it is to implement though.
  11. @jonp Ive been under the impression for a long time that latency and performance improvements in QEMU needed the Q35 machine type to be taken advantage of. All development ive seen, and tips to improve performance, all seem to be around using the Q35 machine type. At the end of the day, I want to get as close to bare metal performance as possible, thats my aim. Im in no way preaching that we should all move to Q35. Now i have my own performance numbers pre and post patch, i'll happily test the i440fx machine type too. Ive also posted this over in the Level1Tech forum to ask them the same question, seeing as its them who've pushed for the development on the Q35 machine type to get these PCIe fixes in the first place. As for removing the option in the GUI for Q35 for windows... I think it would be more appropriate to show a warning if Q35 was selected, as apposed to remove the ability to choose it altogether.
  12. Thank you for this. This is a great baseline to compare my Xeon build to.
  13. Im seeing around 5-10% increase in performance on GPU tests with my RTX2080.
  14. Yep, looks like its fixed the driver crippling memory scaling (in windows anyway). Im seeing a 5-10% increase in GPU benchmarks after updating to RC4. Was hoping for more, but it looks like my bottleneck is my aging CPU now! (2x E5-2670). Ive been meaning to put my hand in my pocket and upgrade to a threadripper build for a while now.... Im very interested to see what performance gains you guys are getting after this patch... Thankyou @limetech
  15. Having a build with QEMU from master would benefit everyone, not just you guys with threadripper builds
