Hi Community,
It seems my first message was sorted under a different topic, so i will post it
again.
I, am a developer for a networkdevice-manufracturer in germany,
To enhance the En-/Decryption speed on the embedded devices (here i will use a
for the explanation a PowerPc mpc8314), I upgraded Openssl to 1.0.0e from
0.9.8i.
I was very happy that the AES-speed improved by roughly 10-15% without even
using the new powerpc assembler optimizations for AES(couldnt get them to work
properly, but this is a different topic).
(Measurements made by "openssl speed aes-128-cbc aes-256-cbc")
No Crypto-hardware was used.

aes-256 cbc 8080.35 8510.50 8635.44 8657.24 8578.82
Sadly I had to experience that my MD5-speed dropped by roughly 20-25% again
without using assembler optimization.(Measurements made by "openssl speed md5")

To identify if the problem of the dropping MD5-speed was only caused on my
device I also tested the MD5 speed on my Core i5 Ubuntu 11.04. I used ./config
no-asm no-hw
and then make install.
But even on my Linux the MD5-speed dropped from:

I tested also with "OpenSSL 1.0.0 29 Mar 2010" and "OpenSSL 0.9.8r 8 Feb 2011".
The 1.x.x Version was always the slower one.
So now I wonder how is it possible that the Md5-speed dropped so much.
Hopefully someone can give my inside on this.
Sincerly,
Marius Peschke
I dont know if attachments work so I will post the table with as a text with
tabs.
