-Summary: This is a performance test designed to benchmark the 
-    latency of installing intents and withdrawing intents. (intent 
-    install and intent withdraw are separate operations with 
-    independent time data)

 NOTE: Only scale sizes 1,3,5 and 7 will be functional
 
---In the .params, remove any values in the comma separated list 
-    in the <scale> tag that are above your desired cluster size. 
+Modifying .params file:
+-- Remove any values in the comma separated list in the <scale>
+    tag that are above your desired cluster size.
 
---In the .params file remove one instance of “1,2” from the 
-    <testcases> tag for each value you removed from <scale> (case 
-    1 and 2 are each called once for each scale value)

---In the .params file, change the value in the <max> tag to your 
-    desired scale size (1,3, or 5)
+-- Change the value in the <max> tag to your desired scale size (1,3,5)
 
---In the .topo file, change the <ONOSbench/COMPONENTS/nodes> tag
