Hi,
I might be missing something, but VMware Fusion Hardware version 21 allows 32 vCPU's
See:

So if your VM is booting very slowly when you assign too much vCPU to the guest.. it just might be that your host doesn't have enough free resources available at the host level?
There are some virtualisation solutions where you can assign ALL host CPU to the guest and it won't affect the guest much in a negative way.
With VMware however, if you overcommit your guest CPU wise, it doesn't get faster.. it gets slower.
That's because if you take too much CPU away from your host, it will have trouble scheduling the guest(s).
My suspicion is that this is what you're seeing.
I might however be completely wrong (wouldn't be the first time).

Subject: future updates vCPU
Does anyone think broadcom will have future updates to Vmfusion and uncap the vCPU.
numvcpus = "4"
cpuid.coresPerSocket = "4"
is just too **** slow on boot for me
