wptdriver using 100% cpu


We have WPT setup on virtual machines and have been noticing the driver sits at using 100% cpu for long periods of time. This only seems to be an issue on VMs that have access to multiple cores, is this a known issue with the driver? Or have we set something up wrong?

Is that from the perspective of the guest or from outside of the VM? CPU utilization inside of a VM tends to be a bit screwy because the host only supplies it the CPU cycles it needs so it can look artificially high.

I’m not aware of any issues.

FINALY. That solved my problem. Seems like wptdriver isn’t very happy with several cpu cores. Setting affinity on wptdriver.exe to only run on one Core fixes all isssues with crashes/freezes/strange results.
