Status in “openssl” source package in Quantal:

Bug description:
  [Impact]

   * Enable arm asm optimisations.
   * This is an SRU as part of Hardware Enablement.

  [Test Case]

  * Compare `openssl speed` on armhf. There should be noticeable
  improvement.

  [Regression Potential]

  * This change affects only arm[hf|el].
  * The test-suite passes correctly.

  [Other Info]

  Openssl has some rather nice arm assembler optimizations. For example
  on pandaboard (omap4430):

  benchmark    debian       with patch
  sha1         55836.67k -> 73599.08k
  aes-128 cbc  18451.11k -> 36305.34k
  aes-256 cbc  13552.30k -> 27108.31k
  sha256       20092.25k -> 43469.45k
  sha512       8052.74k  -> 37194.28k
  rsa 1024     1904.2v/S -> 3650.5v/s
