The following mechanisms are disabled in the sunpkcs11-solaris.cfg file:

# the following mechanisms are disabled due to performance issues
# (Solaris bug 6337157)

We should investigate whether these performance issues are still a concern, and consider re-enabling these for JDK 9.
Originally filed because of poor T1 performance, T3 still produce low numbers. Signing performance was 286 ops/sec for native libraries while 3468 ops/sec for SunJCE. On T4 the performance with native libraries the performance is the same as SunJCE, roughly 5200 ops/sec. Currently Solaris 11 ucrypto supports the above RSA HMAC algorithms. Because the Ucrypto provider is before SunPKCS11 on the providers list, the disabling is ineffective. While this is a degradation for S11 using JDK 8 on T3 and below, it is not a problem on new and currently shipping sparc hardware. Looking toward the future, I believe it is ok to re-enable for JDK9, but unwise to backport the change as we risk hurting performance on established T3. JDK8 should be left as is as it is a good transition release between S10/S11-T3/T4 hardware. T3 and older hardware will be replaced and it is not right to perpetuate the disabled mechanism for a dying hardware line in future JDK releases.
