With the speed of the Geode CPU in a 5501, you'd likely not see a significant (if any) improvement in speed when using userland programs like OpenSSL with onboard crypto accelerators. The context-switch from userland to kernel for the crypto processing will be much more expensive than the crypto itself. I ran some old benchmarks of the crypto processor in the Geode LX (can't seem to find them now), but with a patched OpenSSL I didn't see any real improvement versus letting software do the whole thing. In short, crypto accelerators in SBCs like the Soekris are more for in-kernel crypto processing (like aes-encrypted disks and IPSec), and less for userland processing. Obviously I don't know what you're trying to do with OpenSSL, but in my own experience having crypto accelerator support in userland gave me no measurable benefit. -Proto _______________________________________________ Soekris-tech mailing list Soekris-tech@lists.soekris.com http://lists.soekris.com/mailman/listinfo/soekris-tech
