[Bug 940230] Re: openssl on 64bit is much slower than before

[cc]

Can you post some numbers to compare?  Post the output of   "openssl
speed aes" for different scenarios at a minimum and specify your
processor type.

There should be a comparison of both 32bit to 64bit on precise (which is
what I think you are comparing) AND a comparison of ssl performance on
precise and earlier distributions.

Here are the results of my latest round of testing, my hardy results are
from a 32bit build:

So looking at the results of aes-128 (which arguably is more important
currently than -192 or -256 because of wider usage), results of 16 - 256
bytes are off significantly.

Title:
  openssl on 64bit is much slower than before

Status in “openssl” package in Ubuntu:
  New

Bug description:
  Posting output of openssl speed on precise alpha and 10.04. Some quick
  googling seems to indicate issues with 64bit asm vs. the C version
  (might be a good idea to disable 64bit asm). This is on a processor
  without AES-NI (which is still very common).
