Hi,
We tried to build 0.9.7b version of openssl on the 64-bit
IBM eServer pSeries 6C4 with POWER4+ processor in 64-bit kernel mode
(running AIX 5.2) and we were rather surprised to see that 32-bit
mode executable ('openssl speed') is faster (in block ciphers) than
64-bit executable. (in first case everything was build with target
aix43-cc, in second case it was aix64-cc)
Please can anyone comment this ? (benchmark results are below)
Thank you
Vlado
