Good Morning,

 

After 2 days struggling to increase vm performance, i need help.

 

I have read every single thread about fixing common problems, unraid wiki, cpu pinning, cpu pairing etc...but i just cannot tweak this to have a decent performance. This is my setup

 

asrock pro 3 gen 3

Xeon e3-1260L 

8 gig ram

GTX 1060 

 

This is my VM config

and this is my syslinux.cfg

I have tried Windows 10 and Windows 7 with better benchmark in windows 7 but overall performance better in windows 10.

 

I have tried giving it 7 gigs of ram and 4.

 

I have passthrough my all SSD drive with almost same results.

 

Tried with hyper-v on and off

 

Its seems like with any task my cpu load, memory load and disk load go 70-100%.

 

I dont have the screenshot but even downloading a game from Steam my disk goes 100% with only 20mb/s and also my cpu goes 70%.

 

I really want this system to work. Any help appreciated.

 

I have run passmark and for cpu it gives me 3k-4k result when this cpu can go 6-7k. Only GPU seems to work fine and give good results, everything else is slow.

 

Sorry for my bad english, i am learning.

 

Best Regards,

Joao.

You gave it half a processor, and your benchmark results show that of about half a processor score. so what's the problem there?

 

 

did you put your domain folder in the array? because this isn't a passed through ssd:

 

    <source file='/mnt/user/domains/Windows 10/vdisk1.img'/>

 

and if your domain folder is on the array, then that's why your disk chokes at low speeds. vm's should be on a cache disk, either ssd or spinner, or placed on an unassigned device/disk.

Sorry, didnt see you replied to me, i forgot this post days after

 

Where does it says i only use half a cpu? I am lost, i thought my config is all cpu and dedicates half cpu with this line 

 

Could you help me with my config so it uses all cpu? Thanks

append isolcpus=2,3,6,7 initrd=/bzroot

You assigned the vm to use 4 threads (vCpus). Your processor has 8 threads (vCpus). If you want it to use the entire processor, then you need to assign all 8 threads (cores) to the vm. 

 

Isolating cores via the syslinux.cfg just keeps unraid from using them. If you're not running much else, then you can isolate cores 1-7, leaving unRaid to operate on core 0.
