Hi,
I imported the VPS from Parallels 18 and removed every Parallels 18 drivers. I see that the network is slow ( 50%-70% lower ) and the disc is slow ( for example the file explorer show later the icons and files ).
I putted off the debug and I configured 12GB RAM / 8GB video and 4 vcore. All is lower than physical machine and all is fast on Parallels 18.
Thanks.
