Any decision on this? The stopgap is not that hard. Disable ASM for 64bit and retest to see the performance numbers. -- 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

[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

** Tags added: performance ** Description changed: 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

Just a reference, I've seen something similar at bug 963420, but my initial tests have not shown significant difference in i386 compared to amd64. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/940230

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.
