March 25, 20224 yr How relevant is Post #1 in 2022 on 6.9.2 though? I'm just curious as I got all cores/threads checked for my 5950X and dont see any kind of performance issues?
April 21, 20224 yr Thanks, worked out, wondered me a little cause i thought i made that before and had errors on my vm´s when trying to start them, must been a failure by me. working actually a little better now when the gaming vm is in use so the other can be used a little better. admiral casino biz Edited January 8, 20242 yr by fazaliuyt
March 27, 20233 yr Wondering if someone could recommend how I may increase performance in a VM with a Intel® Avoton C2750 Octa-Core Processor on an ASRock C2750D4I mb which has single thread pairings. I've tried googling it, but can't find much information what would be the proper or recommended way to pin the CPU. The main purpose of the server is to run Plex and dockers, but as of recently I am trying to set up a VM to run Power BI and Excel mainly.
March 28, 20233 yr I am sure, it has been asked before, but can I change machine type from Q35 to I440vx for existing VM? Do I need to change something in VM setting or will it work on the fly?

Do I need to change something in VM setting or will it work on the fly? as this is more or less just the "chipset", yes, it should work, may just needs some new drivers then ... but, just to be safe and as its so easy ... shut down your vm, copy the vdisk image as backup, change mashine type and see what happens, if all is ok, just wipe the vdisk image backup, if not wipe the non working one, move back the original one, change back your vm setting and all is like it never happened ... or, after copy, just setup a new vm with your changed i440 setting and use the copied vdisk ... if all is ok, wipe the "old" vm ...
March 18, 20242 yr If you are curious to see how your CPU is handle in unraid the following two commands can show you dies layout for CPU isolation. For the chiplet designs coming out is best to put your workhorse vm on a single chiplet intead across multiple.

May 18, 20242 yr Can someone please explain this to me? I have my VM set to 8 cores, but in the XML view under "cpu" , it looks like its set to use only 4 cores and 2 threads. <cpu mode='host-passthrough' check='none' migratable='on'> <topology sockets='1' dies='1' cores='4' threads='2'/> <cache mode='passthrough'/> <feature policy='require' name='topoext'/> </cpu> I dont understand why that is when just above that section I have this: <vcpu placement='static'>8</vcpu> <cputune> <vcpupin vcpu='0' cpuset='20'/> <vcpupin vcpu='1' cpuset='84'/> <vcpupin vcpu='2' cpuset='21'/> <vcpupin vcpu='3' cpuset='85'/> <vcpupin vcpu='4' cpuset='22'/> <vcpupin vcpu='5' cpuset='86'/> <vcpupin vcpu='6' cpuset='23'/> <vcpupin vcpu='7' cpuset='87'/> </cputune>

May 18, 20242 yr 6 minutes ago, alturismo said: HT setup ... 4 cores "Hyperthreading" Shouldn't it be 4 cores and 4 threads, not 2 with my above settings? I have 8 total selected. EDIT: I initially configured this though the "form view" and just happened to notice the way the xml was configured as 4 core and 2 thread. I was surprised by that cause I thought it should read 4 thread. Edited May 18, 20242 yr by spotopolis

May 18, 20242 yr 5 minutes ago, alturismo said: nope, 4 core with each 2 threads ... its correct like this sample Gaming VM here Aaaah. I understand now. Thank you for the clarification. I see what you are saying. I hadn't considered it was listing it as 2 threads per core. I figured since it displayed the total number of cores, it would display the total number of threads. I was thinking my configuration was somehow corrupted and had mismatched information.
August 22, 20241 yr A few days ago I set up a Win10 VM for iTunes backup purposes. The VM settings followed the configuration in the first post (pinning cpu cores, pairs for hyperthreading and not using the first two). 4GB of ram and vdisk on my cache SSD. After all of this I still find that the VM is extremely slow to use, almost unusable. I don't know what else to tweak because it seems like the configuration ticks all the boxes for usable performance.
August 22, 20241 yr 2 hours ago, Mad_cyclist said: I don't know what else to tweak because it seems like the configuration ticks all the boxes for usable performance. you definately shouldnt use ballooning RAM in Windows and 4 GB aint that much anymore anyhow, but still should perform reasonable ... and after installing the VM, you prolly use the web VNC ... if so, see this more as "Installation" only ... then use RDP, or at least install nativ VNC Server and connect with a VNC Client ... while RDP will always perform better. and this thread is more about "fine tuning" ... for like Gaming VM's ...
October 26, 20241 yr Just wanted to share some numbers for those with E & P cores and looking for an understanding of their relative speed. Cinebench R23 Multithread using 4 threads on an overclocked 12600k with XMP enabled: 4 threads on 2 P Cores (HT) = 4764 (typical use) 4 threads on 4 P Cores (no HT) = 6993 (+46%) 4 threads on 4 E Cores = 3768 = (-20%) E Cores are no slouch. They are alone faster than Intel Core i3 8100 Edited October 26, 20241 yr by dimes007
February 5, 20251 yr Hello everyone, I'm seeking your opinions to make sure I haven't gone off track with optimizing my Windows 11 VM. I have a Ryzen 7 5800X, and I've configured CPU isolation like this: Which translates to this in the XML: <vcpu placement='static'>10</vcpu> <cputune> <vcpupin vcpu='0' cpuset='3'/> <vcpupin vcpu='1' cpuset='11'/> <vcpupin vcpu='2' cpuset='4'/> <vcpupin vcpu='3' cpuset='12'/> <vcpupin vcpu='4' cpuset='5'/> <vcpupin vcpu='5' cpuset='13'/> <vcpupin vcpu='6' cpuset='6'/> <vcpupin vcpu='7' cpuset='14'/> <vcpupin vcpu='8' cpuset='7'/> <vcpupin vcpu='9' cpuset='15'/> </cputune> I have a doubt about the arrangement of the core/hyper-threading pairs. Thank you for your responses, have a great day, everyone! Edited February 5, 20251 yr by BœufLord
February 26, 20251 yr Hi. I'm wondering if with isolcpus and emulatorpin it's possible to force unraid to only use ecore. Leaving pcore strickly for VMs.
