Unusable performance of Graph view in virtual machine?

I’m running GlassWire in two separate VirtualBox 4.3.26 VMs on a beefy MacBook Pro. In both Windows 7 (64-bit) SP1 and Windows 10 Technical Preview, the Graph view in the GlassWire GUI slows down the VM to an unusable state. The best way to reproduce it is to click on an activity on the graph–it takes about 15 seconds to be able to dismiss the activity notice, and longer to switch the GUI to one of the other views in order to regain any control over the system.

Task Manager shows processor spikes no higher than 30%, and RAM usage steady. Increasing RAM in the VM does not change the behavior.

Does anyone have any suggestions for making the experience usable in a VirtualBox VM?

We’ll do more testing on virtual machines in the future. One way to improve performance would be to delete your graph history by going under the top left GlassWire menu and choosing “settings”. Then set history to “All” and click “Clear”.

Also if you are using torrent apps or similar apps that have lots of simultaneous connections it can cause GlassWire to use more memory than usual. We’re planning a major update that helps solve this.
