Performance Difference Between ESX and ESXi

nhidalgo asked
Last Modified: 2012-05-07
Has anyone seen a performance difference between the two version of ESX? I have a dell R905 running ESXi on a embedded usb. I was wondering if it would run better if on loaded ESX on local 15k drives instead.

I have been doing some bench marks with the R905 with native windows, compared to an R905 with exsi4 and a 2003 vm on top of it and the vm gets about 1/3 the native disk performance. Not sure what the problem is. THe are both connected to the same Fiber channel SAN
