Thanks for your help everyone ! I've checked T5120 hardware specifications : 8 cores 8 threads/core so I used the multi 64 option :
sign verify sign/s verify/s rsa 512 bits 0.0000s 0.0000s 121283.7 202718.0 rsa 1024 bits 0.0000s 0.0000s 30643.1 115804.2 rsa 2048 bits 0.0002s 0.0000s 5282.8 44109.6 rsa 4096 bits 0.0421s 0.0009s 23.7 1071.3 It looks much better ! Does it look relevent to you ? About the multi 64 option : I tried multi 70 to be sure there will be always a thread waiting to be executed. I've noticed some improvement but not much ... Is this a good idea ? -- View this message in context: http://www.nabble.com/UltraSPARC-T2---OpenSSL---PKCS11-----tp24952022p25002897.html Sent from the OpenSSL - User mailing list archive at Nabble.com. ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org
