Hi,

=A0 = =A0I've noticed that, at least in my enviroment (Cassandra 1.1.12 runni= ng on Amazon EC2), decommission operations take about 3-4 minutes while boo= tstrap can take more than 20 minutes.
=A0 =A0What is the reason to have this time difference? For both opera= tions, what it is time-consuming the data streaming from (or to) other node= , right?
=A0 =A0Thanks in advance.
