ESX Performance

Will adding a CPU reservation help in a situation where I have multiple ESX guests that are 90% CPU utilized, with high wait and ready Times +3000 ? I am thinking it will. The overall performance on the ohysical boxes is 30% utilized. Each physical has 20K Cyles of 45,483 available? The boxes are made up of 4 Quad core processors? Why are the Physical boxes not busier? if there are high wait times..

Is this enough info..

Do you have multiple vSMP VMs? I would guess scheduling conflicts. Adding more hosts should reduce that, but first I would try to identify if that is the issue. start by looking at esxtop.
