+|test purpose  | To evaluate the IaaS compute capability with regards to      |
+|              | cache utilization.This test case should be run in parallel   |
+|              | to other Yardstick test cases and not run as a stand-alone   |
+|              | test case.                                                   |
+|              | Measure the cache usage statistics including cache hit,      |
+|              | cache miss, hit ratio, page cache size and page cache size.  |
+|              | Both average and maximun values are obtained.                |
+|              | The purpose is also to be able to spot trends.               |

-# Measure cache hit/miss ratio and usage, network throughput and latency.
-# Different amounts of flows are tested with, from 2 up to 1001000.
-# All tests are run 2 times each. First 2 times with the least
-# amount of ports, then 2 times with the next amount of ports,
-# and so on until all packet sizes have been run with.
-#
-# During the measurements cache hit/miss ration, cache usage statistics and
