Yes. Although the changes to POIFS will not have a tremendous initial impact on performance since HSSF will still be buffering all of the records (I have ideas for changing that, but it is a lot of work).
I was suspecting this to be the case. I was hoping that the performance would be comparable at least and that memory usage would be the same or better. If this is the case we could pick your implementation and run with that and then work towards providing an implementation of HSSF that can take better advantage of the new API.
