In case you are running Avast or AVG antivirus on the host machine, you should turn off the hardware virtualisation feature. If you are using BitDefender 2017 or later, also has some virtualisation feature that interferes with running of VMs but it seems to be the only way is to uninstall.
For AVG, refer to this post Re: XP VM suddenly slow, Win 7 fine
For Avast, refer to this post Re: XP VM suddenly slow, Win 7 fine
From the log, you are use version 12.1.1 which is quite old. If you want to try 12.x version use the last release on that line by updating to 12.5.9.
It also seems that you have dual E5-2650 v2 Ivy Bridge CPUs and configured the VM to use 2 virtual sockets, 4 cores per virtual socket for a total 8 vCPUs. You should only allocate the number of vCPUs that the VM can realistically utilised. Idle CPUs, especially if there are more idle than busy ones, can have a perverse effect of bumping the busy vCPUs.

If it isn't the antivirus stuff, try reducing the number of vCPUs and use 1 virtual CPU socket. I don't know how well VMware Workstation 12.x/14.x handle dual CPUs; but using 2 virtual sockets, from the log, it seems to automatically enable virtual NUMA.
