You were likely seeing I/O wait and resource issues when using the 
terminal output, and likely coupled with a large number of stream 
errors.  You should not be running at high verbosity levels (using only 
the default for normal operation--which means -v important,general).

As far as the slow response...  Well, I am certain that response will 
vary with system resources.  A different computer with more 
memory/faster CPU will likely respond much more quickly.
