With vSphere 6.5 you can now take advantage of the AVX (Advanced Vector Extensions) CPU instruction set. With AVX extensions, the CPU can execute up to 256 doubles, which are 32-bit floating point values in IEEE754 standard format. Each VM in a vSphere datacenter can have its own 128 MB of memory that is allocated in 4 8 MB page size. If you take a closer look at this, we are now using 32-bit floating point values instead of 16-bit floating point values. Even though we are using the same amount of memory, we have more performance per unit. AVX extensions are not available by default in ESXi.
VMware.VirtualMachineManager.MaximumMemoryOvercommit= VMware vSphere Hypervisor ESXi 6.5.0-4887370 x86 64 ISO (2017) crack Swapping under an overcommitted virtual machine is a resource-intensive operation that can significantlyreduce the performance of the virtual machine. Maximum memory overcommit can be specified at thehost level, so that ESXi does not swap memory for the overcommitted virtual machine, or swappages the memory at the virtual machine level to reduce the impact of the swapping.
ESXi can read host-level memory parameters from the datastore which hosts the virtual machines todetermine the maximum memory allowed at the virtual machine level. This parameter is calledBypassVmMaxMemory, and is set at the host level in the datastore file:

This parameter is called VmMaxMemory, and is set at the host level in the datastore file: 3d9ccd7d82
