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.
