Thanks a lot for the quick review and suggestions to improve the code
We incorporated all the changes but didn't see any improvement in the
However, we finally noticed that it was the packet size used in our
simulations that was affecting the throughput. It was earlier set to 1000
bytes, and after making it 1500 bytes (including headers) we note that the
throughput is not affected.
We have uploaded the new graphs on the same wiki link:
We're not sure why packet size is affecting the throughput so largely. Is
it the expected behavior?
Thanks and Regards
