We are virtualizing our Oracle 11gR2 databases (running on OEL57 64-bit) on Vmware 5.1. I've read information at various locations that hyperthreading is not recommended for Oracle 11g database. One example is here, however, I seen many more:

My issue is that Vmware themselves recommend enabling hyperthreading for virtalized Oracle databases in their Oracle Databases on VMwareBest Practices Guide.
Does anyone have any practical expierence with this issue that can be shared? What are the advantages and disadvantages of enabling hyperthreading for our virutalized Oracle 11gR2 on OEL57 64-bit virtual machines
Thanks, Fred
