You have GC logging turned on, and it appears GC is working well. [ParNew: 1398632K->345K(1747648K), 0.0062240 secs] Indicates that about 1.2 GB of new objects were cleaned in less than 1/100th of a second. If this is occurring once every second, an application is creating a lot of short lived objects. Check the time stamps and see how often this ...

It sounds as though you're describing the VMware Server 2.0 product from 2009, not VMware vSphere or ESXi. If that's the case, this product has been end-of-life and support for at least 5 years. You shouldn't be using it today. As for the guest VM configuration, VMware Server 2.0 only allowed you to allocate 1 or 2 vCPUs to a guest. There are no options ...
