Why is snapshot so slow?

Why are VM snapshots bad?
In the event that the VMFS volume does fill, the current snapshot file won’t be able to accept writes, and the virtual machine will promptly crash. In an instance where you have a large number of virtual machines with snapshots all sharing the same full VMFS volume, they’ll all crash.
What do you need to know about the snapshot app?
