HIFN benchmark continue.

Hardware: VIA C3 Ezra with 256 Mb of RAM.
Big file copy from unencrypted to encrypted partition.

As you see HIFN results are definitely better. But CPU usage is higher, but that CPU usage is not 100%-what_user_might_use, but instead it is time which copy itself was performed, so if it is higher it is better.

Hardware: Celeron 1.3 Ghz with 504 Mb of RAM.

HIFN is slower here. Probably because of PCI bridge.
