listed in `VPP-17.04 release notes `_. Additionally, vhost-VM performance improvements are due to both VPP code optimizations as well as due to the FD.io CSIT Linux KVM test environment optimizations for vhost-VM tests - see section "2.1.7. Methodology: KVM VM vhost". Other Performance Changes - to be updated ------------------------- Other changes in measured packet throughput, with either minor relative increase or decrease, have been observed in a number of CSIT |release| tests listed below. Relative changes are calculated against the test results in CSIT rls1701 report.
