Very well for stating what you looked at. But actually stating what you saw when looking would have been more helpful. I have seen a few people mentioning that diskd vs AUFS situation has resolved itself in FreeBSD 9 or 10. You could try changing the cache_dir "diskd" to "aufs" or "ufs" and see if the speed increases. NP: Only a -k reconfigure is needed moving between those three types.
