While trying to diagnose a performance issue with my software, I noticed that sha1 performance on Solaris has taken a huge hit since 0.9.6b ( I am upgrading a very old client program ).
After running some speed tests, I found that in 0.9.6b sha1(64) was 14762k but in 0.9.8j it is only 6593k ... less than half. I did a little more work to find that later versions of 0.9.6 also suffered performance issues due to the introduction on OPENSSL_cleanse() ... replacing that method with a simpler model ( for testing ) brought performance back up. But, with 0.9.7, 0.9.8 and 0.9.9 snapshot, replacing the cleanse function does not help. And, although the assembly language changes in 0.9.9 dramatically improve RSA performance, sha1(64) has sunk even lower than before ... clocking in a measly 4992k. So, I was wondering if there were any plans to address this trend, or anything I can call or configure to help ... at this point, my only immediate choice is to use old code from 0.9.6 since I cannot afford the performance hit with anything newer. -- View this message in context: http://www.nabble.com/poor-sha1-performance-on-Solaris-8-tp21485121p21485121.html Sent from the OpenSSL - Dev mailing list archive at Nabble.com. ______________________________________________________________________ OpenSSL Project http://www.openssl.org Development Mailing List openssl-dev@openssl.org Automated List Manager majord...@openssl.org
