##### SUMMARY
<!-- Explain the problem/feature briefly -->
With Ubuntu 20.04(KVM)+ACS 4.15, we noticed
- Access to Windows guests via NoVNC console is extremely laggy, barely to
use. Even compared to the original
- Access to Linux guests via NOVNC consoles however, looks pretty smooth,
no any issue
