That page specifically says you don't have to disable LRO if you are above 4.1 esxi and 8.6 CUCM.
Martin, which version of 5.5 are you on? GA, update 1 or 2? I recently ran into an issue with a customer on 5.5 u1 and too new of raid drivers on the card and had to downgrade the drivers. Wasn't causing 100% cpu, but very slow drive access times. So checked your vmware version and compatibility on the hardware you are running.
