about header compaction in beta 15

It's running faster than 6.56 which is very nice. I was wondering: Does any of the performance options affect NB's db access speed?
The raid array I have the NB db on can write at 200MB/s under heavy load from two arrays. NB while accessing the db files and actively compressing with no other programs accessing the db is only writing at 8-20MB/s and the disk load is not even reaching 50%, the cpu is around 8% with spikes to 20%, on only one thread. The array while being accessed by other 2 other arrays can easily read at 500MB/s simultaneously. Any way I can speed it up?
Also the logger reports being stuck on compressing boneless, but resource monitor states NB is accessing and writing warez, x, and worms.
All three groups were accessed after boneless but the verbose log did not update to reflect that. I'll keep an eye and see if it does that again.
I will say this compressing 225 groups and only taking 40 minutes vs hours on the old versions is mighty nice!
