Bug Description
Currently the producer/IO thread pulls N transactions at a time from the master between each sleep and poll. This is to keep memory usage at a minimum. What it really should do is continuously pull N transactions until no more are available, then hit its sleep cycle. This would allow it to catch up to the master as fast as possible.
