Currently I'm noticing a horrible performance when I put my VM's on my internal HDD. The HDD is split into 3 Partitions (D:, E:, F:) and have a maxiumum capacity of 500GB by 7200rpm.
File copy from the M.2 SSD to the HDD and vice versa is pretty fast (around 115 MB/s) but as soon as I start a VM the usage stuck between 98% - 100%. For now I have no idea what is causing the behaviour and I don't know if this is normal.
Further more information about the host system:
- OS: Windows 10 1809
- CPU: i5-8250U (yes, it is a laptop)
- RAM: Single Bank 8GB DDR4 2400MHz
- SSD: M.2 Samsung EVO860 (256GB)
- HDD: 500GB 7200rpm (about 8 - 10 years old)
- Hypervisor: VirualBox
For any idea I would be thankfull.
Performance in a HDD is always way worse than SSD. A VM will add to that. – None – 2019-06-19T20:07:09.563
What OS are you running in the VM? Are you using Hyper-V or Oracle VirtualBox? How much RAM are you allocating to the VM? It sounds like a paging issue, in that the VM is just paging to disk as it's out of RAM. – spikey_richie – 2019-06-19T20:07:28.090
@spikey_richie Oh crap! Sorry I forgot to name the hypervisor. It is VirtualBox. I only test Win Server 2016 Standard for know. I gave it 2Gb of RAM what was sufficient while running the VM from the SSD. – MarvinMcFly – 2019-06-19T20:11:06.460
1Right, but paging out to the SSD would be OK as it's performant. Paging to a regular HDD is not. What if you allow the VM to use 4GB or RAM? – spikey_richie – 2019-06-19T20:12:38.400
@spikey_richie Yeah that’s an idea. Further I will turn of the swapping hopefully it will give a benefit instead of problems. I will update the question tomorrow – MarvinMcFly – 2019-06-19T20:14:52.273
What's the verdict? – spikey_richie – 2019-06-20T14:07:12.750
