Any decision on this? The stopgap is not that hard.

[Bug 940230] Re: openssl on 64bit is much slower than before
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: http://pastebin.com/XrFUT8Zq 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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/940230 Title: openssl on 64bit is much slower than before To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssl/+bug/940230/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 940230] Re: openssl on 64bit is much slower than before
Here's a post that talks about the old assembly for 64bit x86. http://zombe.es/post/405783/openssl-outmoded-asm Performance is up to 50% worse for AES ciphers so I would think this is a must fix. Patch available for RC4 on x86_64. http://cvs.openssl.org/filediff?f=openssl/crypto/rc4/asm/rc4-x86_64.plv1=1.12v2=1.13 For the rest, the option should be to disable ASM for 64bit and rely on AESNI for processors with AES-NI support.
