What's surprising me is the fact that I had VirtualBox with almost the same setup installed on my old machine and it was working fast and flawlessly. The new machine is much more powerful, so I'm wondering, what's going on. Here's my setup:
Old machine
- Linux Mint version 18.x, ext4 file system
- VirtualBox in version 5.x with Guest Additions installed
- dynamic memory allocation (about 50GB), sometimes running into problems with the pagefile
- 6-core AMD CPU, 3 of which I had assigned to the guest system
- 16GB of RAM, 8 of which I had assigned to the guest system
- NVidia GeForce GTX 980 with 4GB of VRAM
- Linux Mint version 19.1, ext4 file system
- VirtualBox in version 6.0 with Guest Additions installed (installing 5.x makes no difference)
- static memory allocation (about 128GB)
- HP Z820 with 16-core Intel Xeon CPU, 8 of which I have assigned to the guest system
- 64GB of RAM, 32 of which I have assigned to the guest system
- NVidia GeForce GTX 980 with 4GB of VRAM
Any ideas, what could be causing this? Is there anything that I could try?
Any help would be much appreciated.
