Sebastian, if you're still seeing worse results on powerpc could you
post the actual numbers with/without this patch?

Sure. I test it around Monday.

That was, what I expected as well but the numbers were different. I
checked the assembly code and I had the le loads but more code. I will
check with different compiler maybe it will get better here as well.

If you pull my cryptodev-2.6 tree then you'll be able to run
the above test.
Performance is significantly increased on Niagara2 by using
the little-endian loads inside of the transformation loop, as
expected. The

Not to nitpick, but if you use le32_to_cpup() this will allow the
use of little-endian load instructions on powerpc and sparc.

I know that. Please see my follow up mail with some tiny numbers.
gcc-4.1.1 was used on a mpc8544.
But what do the numbers look like on other architectures? In

David: would you please be so kind to run a test on sparc machine?
How do I run the test?

do you need / want the three patches or do you
