Software Crypto Performance

Interesting results - Solaris 10 08/07 (update 4) on v440, no crypto card.

openssl speed rsa1024 -engine pkcs11 -multi N
openssl speed rsa1024 -multi N

Where N was 1 2 4 8

As you can see even without having crypto card there's huge performance increase by using pkcs11 - different algorithm implementation and different compiler?

Data Corruption

CERN has published a paper on data corruption in their data center.
Here you can find some comment and nice summary for those findings.
