> 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?
