I have a cluster in Amazon cloud , its described in detail in the attachment. What I've noticed is that we during bootstrap we never go above 12MB/sec transmission speeds and also those speeds flat line almost like we're hitting some sort of a limit ( this remains true for other tests that I've ran) however during the repair we see much higher,variable sending rates. I've provided network charts in the attachment as well . Is there an explanation for this? Is something wrong with my configuration, or is it a possible bug?
