Re: [pfSense-discussion] pfSense router/firewall in a Vmware ESXi guest for other guests

[Tim Dressel]

I gave mine a 10GB disk and 512MB ram, and two CPU's on a 4 core ESXi box
(Xeon 3.2). I also ran squid on it. I find that VMware tends to give a
perceived performance hit when you only assign a single core to a VM when
the host is dual core and multi-processor. I'm not sure why this is.
