* '''In all the three cases (1 - idle system and idle VM/CT, 2 - loaded system and idle VM/CT, 3 - loaded system and loaded VM/CT) OpenVZ shows the lowest overhead over all the tested virtualization solutionsand demonstrates latencies close to the native results of non-virtualized systems.'''* '''VM virtualization solutions like Xen demonstrates latencies by an order of magnitude worse then native response times.'''
