There are provided a system and method of assessing latency of forwarding data packets in virtual environment. The method comprises: generating packet signatures SGand SGrespectively for departing and arriving data packets; maintaining a first data structure comprising records related to departing packets associated with a first virtual function (VF), each record informative of SGand registered departure time Tof a given departing packet; responsive to registering arriving time Tof a given monitored arriving packet SGassociated with a second VF, searching the first data structure for a record matching a matching condition SG=SG; modifying the matching record to become informative of latency &#x394;T=T&#x2212;Tand adding the modified record to a second data structure; and using data in the second data structure for assessing latency of forwarding packets from the ingress virtual port to the egress virtual port.
