What is the best way to delete SnapShots in vSphere 5.5?
Is there any step by step procedure or guide that I could be provided? Either thru GUI or CLI.

It's not *SIMPLE* it needs some thought!

1. Is the VM ON.
2. Is there enough storage space on the datastore.
3. WHY is there a snapshot on the VM ?

Please see my EE Article

HOW TO: VMware Snapshots :- Be Patient

What *NONE* of the previous Experts have explained, is what happens, when it ALL GOES *SIMPLY* tits (WRONG) up in their SIMPLY terms.

1. If you delete a snapshot, do EXPECT it to appear as if it hangs at 90, 95 or 99% this is normal!

2. Depending upon how large the snapshot is, and it's worth checking, you do check your VMs every day for snapshots, snapshot growth can be 1GB an hour on an idle machine, if a snapshot fills up a datastore the VM will fail and stop!

3. if you have a large snapshot, it could take seconds, minutes, hours, days, or weeks to commit (delete!).

4. So BE VERY PATIENT.... do not cancel, restart the VM, stop the VM, reboot the host, you could corrupt the VM.

5. So Snapshots SIMPLE, no thy are not they need to be understood and respected, do not use them, and check daily for them!

Finally performance of any VM on a snapshot is POOR!

Based on the comments, which I highly appreciate.  The  SnapShots exists for the VM which is ON and  the performance is very slow.  I know consolidation is going to take a long time, as experienced in the past.  Is there a proper way to delete multi-Snapshots using CLI.

This is to be expected, writing to a snapshot child disk caused poor performance.

Delete ALL the snapshots.

Could you provide me the correct CLI command?
I have followed this link but a little confused as to which one I should run first.
