It may be helpful to watch top while playback is going on, to see if
there's any processes that jump out taking a lot of CPU. Otherwise, make
sure there's no IO issues (watch it with something like iostat) - are both
the MySQL DB and your storage directory on the same drive? If the issue
isn't showing up directly in the -v playback logging, then some of these
other starting points may help...
