+. *Test step:*
+
+F send goal state message to A-E at the same time concurrently after first warming up then wait for the response, goal state message is different in each payload
+
+On A-E there are 2600 ACA running on each box, ACA code has been revised to cut off the ovsdb and mq operations

+. *Test Conclusion*
+
+[loweralpha]
+. *Alcor DataPlane Manager could support more than 10k concurrent ACA grpc requests*
+. *Alcor DataPlane Manager runs well when from 32 threads up to 256 threads for the performance*
+. *A-E hardware configuration could run 2000 stable ACA instances on each box*
