Betreff: Re: via padlock support much slower in 0.9.8e than
in 0.9.8d, why?
Hi!
I cannot confirm these performance differences between 0.9.8d
and 0.9.8e. My results on a Via CPU are:

With a VIA C5 board I get a huge difference in speed with engine
padlock support (same machine same OS etc.).
Where is the difference coming from. Are there any changes
regarding
buffering or block sizes? Look at this results:
