Comparison with native code:

OpenSSL (using native C) (d2i_X509 100000 times): 2.679s

BouncyCastle (using Java 7u2) (bcprov-jdk15on-147.jar X509StreamParser 100000 times): 3.370648707s

JCE CertificateFactory (using Java 7u2) (CertificateFactory#generateCertificate 100000 times): 0.374258382s


Except for the JCE, even native code is notably slower than Krypt. For once, Ruby is faster than native code :)
