He plugin: Stats collection takes long when controller is busy

Bug Resolved Done Unassigned Luis Gomez Sun, 24 Jan 2016 18:38:11 +0000 Mon, 27 Sep 2021 09:01:42 +0000 Sat, 30 Jan 2016 03:49:29 +0000 General 0 2 <p>Stats collection times seem to grow superlinearly with the number of flows. With 100k flows, in my environment (single node, mininet with 15 nodes) it takes 17 seconds to program 100k flows with this command:</p> <p>./flow_add_delete_test.py --threads 8 --flows 12500 --auth --bulk-delete --timeout 10000 --fpr 200</p> <p>It takes 9 minutes and 30 second to finish stats collection for all the 100k flows after the flow programming have been blasted into mininet. The controller was not busy at all, CPU utilization stayed around 20%.</p> <p>The issues I reported have been fixed with He latest patches. Stats collection in He takes half time now, still Li plugin has better stats collection.</p> Development External issue ID 5071 External issue URL Issue Type Rank 0|i0325r:
