Yes, for single thread HDFS client.
No, for well designed map-reduce jobs.

"Normal operation" is a function of hardware.  Giving the version without the underlying hardware means I get to make up any answer I feel like.

I can't imagine a rational set of hardware where 10 megabits (as in, one megabyte) a second is normal.
