I force it it via ssl.cnf


0(achinetboot)% tail -11 /etc/ssl/openssl.cnf

openssl_conf = openssl_def

[openssl_def]
engines = openssl_engines

[openssl_engines]
padlock = cryptodev_engine

[cryptodev_engine]
default_algorithms = ALL
0(achinetboot)%


The limiting factor here for ssh seems to be the 100Mb link my i5 box is
on. Here is with and without aesni loaded

0(achinetboot)% /usr/bin/time scp -c aes128-cbc test.bin
mdtancsa at 10.255.255.1:/dev/null
test.bin
                                  100%   88MB  11.0MB/s   00:08
        8.14 real         0.44 user         0.57 sys
0(achinetboot)% /usr/bin/time scp -c aes128-cbc test.bin
mdtancsa at 10.255.255.1:/dev/null
test.bin
                                  100%   88MB  11.0MB/s   00:08
        8.15 real         1.46 user         0.36 sys
0(achinetboot)%

I will move it to gigabit to get a better test shortly.

 patch -p2 < a
Hmm...  Looks like a unified diff to me...
The text leading up to this was:
--------------------------
|diff --git a/sys/crypto/aesni/aesni_wrap.c b/sys/crypto/aesni/aesni_wrap.c

done


Seems to work ok

But there is a LOT of variation between runs for some reason.

I added to http://www.tancsa.com/fpu.html

the different runs
