If this VM is swapping out memory due to resource contention, it usually means VMKernel does extop have enough machine memory to meet memory demands from all the VMs. Each queue has an associated latency, dictated by its size and whether the IO load is low or high, which affects the throughput and latency seen by applications inside VMs. The possible side effects are a reducing the memory cache used by guest OS, b guest swapping.

Again, note that it is the VMKernel swapping not the guest swapping. Note that the actual swapping is done at the group level.
