Hi Tushar, I found "Message Delayed Cycles" histogram information in ruby.stats, I wonder if the "average" is the latency for each messages. Also, I want to run some synthetic benchmarks to evaluate my new topology with hammer protocol in ruby simple network. I read the wiki page and know that network tester has some synthetic benchmarks, but is supposed to be used with the dummy protocol MI_example, so I start with that protocol. However, in Message Delayed Cycle information part, I find that most messages have 0 delay. I wonder why. It is also like this when I switch to hammer protocol. And for two runs with the same maxpackets injected but very different link latency, the run time is almost the same. I wonder what is the correct way to use the tester with synthetic benchmarks. If this tester is not actual or does not work well with hammer, are there any other recommendation for a few simple benchmarks to run? Thanks.
