July 27, 20232 yr Hello everybody, this is my first post on the forum. I hope this post is in the right section. I've been running UnRAID for a few months now, and it has been running flawlessly. However, I noticed that the download speed in a Windows 10 VM reaches only around the half of the speed when downloading on VPN. If I turn the VPN connection off, the download speed is back to 100%. Since the VPN uses AES-128 encryption, I think the problem may be related to AES-NI instructions not being enabled for the VM. I also tested it on a Windows 10 VM on a Proxmox host, and downloads are at full speed on VPN. Is there a way to enable AES-NI for a Windows 10 VM? How does it work on UnRAID? Thank you for your help.
July 30, 20232 yr Solution Usually, windows 10 vms are configured with cpu hostpassthrough, so if the real cpu supports aes, the aes flag will be passed to the guest too...can you check with cpu-z if aes is listed in the cpu flags?and what is the real cpu? Edited July 30, 20232 yr by ghost82
July 31, 20232 yr Author Thanks for the reply. It seems AES is also passed to the VM. Download speed is good now.. it was just a bad vpn server. It's weird how cpu-z shows processor name "Intel Xeon E5-2620 v4" and specification "Intel Xeon E5-2683 v4". The actual CPU is an Intel Xeon E5-2683 v4. Also windows task manager shows cpu clock 2,10GHz while cpu-z shows 2,6GHz.. Maybe there is a fix for this? Anyway it's working good now, thank you!
