I have seen the problems you describe before. Although a configured cache size of 250M and a database size of some 660M is not sufficient, it still is not such a bottleneck. To my experience a heavy cpu load is most likely based on heavy disk operations. If moving the transaction logs onto a separate disk didn't solve it, look for other concurrent read/write operations. Check whether the logs report constantly deadlocks. In some cases a journaling file system reduced performance. I experienced rather bad results with xfs.
