+**Host CFS optimizations (QEMU+VPP)**
+
+Applying CFS scheduler tuning on all Qemu vcpu worker threads (those are
+handling testpmd - pmd threads) and VPP PMD worker threads. List of VPP PMD
+threads can be obtained e.g. from:
+
+::
+
+ $ for psid in $(pgrep vpp)
+ $ do
+ $ for tid in $(ps -Lo tid --pid $psid | grep -v TID)
+ $ do
+ $ echo $tid
+ $ done
+ $ done
+
+Or:
+
+::
+
+ $ cat /proc/`pidof vpp`/task/*/stat | awk '{print $1" "$2" "$39}'
+
+Applying Round-robin scheduling with highest priority
+
+::
+
+ $ for psid in $(pgrep vpp)
+ $ do
+ $ for tid in $(ps -Lo tid --pid $psid | grep -v TID)
+ $ do
+ $ chrt -r -p 1 $tid
+ $ done
+ $ done
+
