+Profile Your Application
+========================
+
+Intel processors provide performance counters to monitor events.
+Some tools provided by Intel can be used to profile and benchmark an application.
+See the *VTune Performance Analyzer Essentials* publication from Intel Press for more information.
+
+For a DPDK application, this can be done in a Linux* application environment only.
+
+The main situations that should be monitored through event counters are:
+
+*   Cache misses
+
+*   Branch mis-predicts
+
+*   DTLB misses
+
+*   Long latency instructions and exceptions
+
+Refer to the
+`Intel Performance Analysis Guide <http://software.intel.com/sites/products/collateral/hpc/vtune/performance_analysis_guide.pdf>`_
+for details about application profiling.
