I have installed CHR 6.48 using the OVA template on ESXi 6.7.0 Server.
2 CPU (Server has 4 Cores and this is only VM running)
10GB Storage (Paravirtual)
1 Network (VMXNET3)
Anytime Dude is enabled CPU is maxed on 1 core. Fresh install with no devices in Dude.
Disable Dude and it goes back to normal CPU usage.
