Yes, hyperthreading is recommended on ESX. An ESX/ESXi host enabled for hyperthreading should behave similarly to a host without hyperthreading. You

might need to consider certain factors if you enable hyperthreading, however.

Please read the section Hyperthreading in Resource management guide to know these factors and to know more about Hyperthreading on ESX.

I normally recommend against it unless it is nehalem. So far I haven't seen much performance improvements when it came down to HT, with Nehalem there seems to be an improvement which can be up to 20%.
