This is because improvement for longer # keys is not high enough to justify the effort, highest measured # was ~5% on Westmere. [This is relative to OpenSSL 1.0.2, upcoming # for the moment of this writing!] Nor does this module implement # "monolithic" complete exponentiation jumbo-subroutine, but adheres # to more modular mixture of C and assembly. And it's optimized even # for processors other than Intel Core family (see table below for # improvement coefficients). # # # RSA1024 sign/sec this/original |this/rsax(*) this/fips(*) #
