[ic] [bounce] extremely slow after 5.7.6 upgrade

[Grant]

I upgraded from 5.6.1 to 5.7.6 a few weeks ago.  I just noticed that
the [bounce] tag is taking an extremely long time to execute, maybe
between 30 and 200 seconds.  It was fairly instantaneous on 5.6.1.
For example:

http://www.example.com/page.html

redirects to:

http://www.example.com/otherpage.html

with:

[bounce href="[area other_page]" status=301]

I've tried without the status parameter with the same results.  Does
this sound familiar to anyone?
