Measured improvements are in line with VPP code optimizations listed in
`VPP-17.04 release notes
<https://docs.fd.io/vpp/17.04/release_notes_1704.html>`_.
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.
