Hi Isha,

There is an existing suggestion SERVER-4355 to allow multiple migrations at once. Please upvote and watch this issue for updates.

Thanks,
Stephen

Over time we definitely will allow multiple migrations in flight as the same time.
Its tricky balancing chunk migration performance, with impact of balancing on cluster performance.
Is your system overloaded and that is why its slow, or is it slow for other reasons?
