I did observe more than 20% on Opteron, but on Core2/Sandy Bridge
I get only 13-11%...
Well, I've got 984 / 1170 clocks on Core 2 (17%)
and 1033 / 1250 on Core i5 (Westmere) (18%)
Out of curiosity, how fast is updated code from CVS on Westmere?
Sorry, too many codenames. It is Lynnfield.
I
modified the 'Configure' script to allow the compilation of a 32bit
version of openssl *with* the assembly routines.
What does it mean? Configure supports 32-bit builds *with* assembly as
it is. To build 32-bit version on 64-bit Linux, run './Configure
linux-elf -m32'.

here are the raw 'openssl speed sha256' results with and without the
patch; all I did was
tar xzf openssl-1.0.0j.tar.gz
cd openssl-1.0.0j.tar.gz
apply patch or not
./Configure linux-elf -m32
make
cd apps
./openssl speed -evp sha256 | grep ^sha
./openssl speed sha256 | grep ^sha
And the result exactly for Lynnfield is unexpected,
Don't you feel sometimes that Intel mocks you? :-) :-) :-)

see below:
clocks for 1.5 / 1.6 / my version:
Core2 1170 / 1131 / 984
Core i5 1250 / 1430 (!) / 1033
Ouch! http://cvs.openssl.org/chngview?cn=22597.
Core i5 1.7 is 1270
