I'm not sure what you guys' expectations are, but if you're restoring 5
minutes worth of database traffic in 8 seconds I wouldn't be complaining.

Depending on your transaction mix and what percentage of it is read-only
select queries you might reasonably expect the restore to take as long as it
took to generate them...
