It really is going to depend on what test you are running. HT has the greatest effect when the running process has a lot of "downtime" for things like memory retrieval or any I/O as it allows for other processes to make use of this downtime. So if your tests are just doing calculations with very little file/network I/O it could very well be in the 9% range.
