Are your VMFS volumes block aligned? For optimal disk I/O utilization & performance they should be. You can find out in the ESX Service Console with the following command:
fdisk -lu /vmfs/devices/disks/[vmhba_path]
A start value of 63 indicates no VMFS alignment (not optimized)
A start value of 128 indicates VMFS alignment (optimized)
