Jayapal Reddy commented on CLOUDSTACK-2433:
-------------------------------------------
Please find the below test results for the RPS/RFS.
Created the VR with 4 cores and 1 MB RAM.
netperf command:
netperf -H 10.146.0.134 -l 60 -n 4
netserver is running two hosts 10.146.0.134 and 10.147.59.206.
>From the VR run netperf command to send traffic to two netservers parallel.
With the basic tests I could not see big difference in the results.
Run the netperf command by changing the various options but in my test setup I
did not much difference.
With RPS/RFS enable
