I have Win2000 guest OS running on ESX (datastore on HP EVA4400 SAN). After upgrade the ESX to version 4.1, the batch job runs 10 times slower than before. I have identical server that running ESX4.0, migrate Win2000 guest OS to ESX4.0. The batch job runs normal.
I wonder why the performance in ESX4.1 is much slower than ESX4.0. Is there any unsupported feature for Windows 2000?
