For best performance, it is recommended that each machine has two adapters, one mapped to the real IP address and one mapped to the virtual IP address. This is because, on a single adapter machine, if you configure NLB in Unicast mode then the adapter will be only in NLB use, no other network traffic could use that adapter but if you configure NLB in Multicast mode then all traffic would use that adapter and hence degrade the performance due to load on single adapter.
